Peraturan Bersama Menteri Agama dan Menteri dalam Negeri Nomor 08 dan 09 Tahun 2006 Tentang Pendirian Rumah Ibadat (Kajian dalam Perspektif Hak Asasi Manusia )
Pundamental 1945 Constitution as the rule has been set explicitly for religious freedom in the run by followers, who belong to one human rights has, but in reality the persecution of religious life and often inevitable. Between religious persecution can come from various directions such as harassing each other, mutual intimidate(violence) and that most often occurs between religious persecution that is prihal establishment synagogue. Therefore, in terms of the establishment of the synagogue there must be government intervention to regulate it, if in this case given the freedom and without any clear rules, the sectarian conflict will not be able to avoid. One step from the government to avoid conflict in the establishment of the synagogue is to be issued the Joint Decree of the Minister of Religious Affairs and the Minister of Home Affairs Number 08 and Number 09 Year 2006 About the Construction of Houses of Worship that aims to create harmony and peace between religious and have certainty Strong law
MagneticāNonmagnetic Phase Transition with Interlayer Charge Disproportionation of Nb<sub>3</sub> Trimers in the Cluster Compound Nb<sub>3</sub>Cl<sub>8</sub>
We
grew large single crystals of the cluster magnet Nb<sub>3</sub>Cl<sub>8</sub> with a magnetic triangular lattice and investigated
its magnetic properties and crystal structure. In Nb<sub>3</sub>Cl<sub>8</sub>, the [Nb<sub>3</sub>]<sup>8+</sup> cluster has a single unpaired
spin, making it an <i>S</i> = 1/2 triangular lattice anti-ferromagnet.
At low temperatures, Nb<sub>3</sub>Cl<sub>8</sub> exhibits a magneticānonmagnetic
phase transition driven by a charge disproportionation, in which the
paramagnetic [Nb<sub>3</sub>]<sup>8+</sup> clusters transform into
alternating layers of nonmagnetic [Nb<sub>3</sub>]<sup>7+</sup> and
[Nb<sub>3</sub>]<sup>9+</sup> clusters. The observed exotic phenomenon
with the strong correlation between the magnetism and structure are
based on the nature of the cluster magnetism
Linear Coordination Fullerene C<sub>60</sub> Polymer [{Ni(Me<sub>3</sub>P)<sub>2</sub>}(Ī¼āĪ·<sup>2</sup>,Ī·<sup>2</sup>āC<sub>60</sub>)]<sub>ā</sub> Bridged by Zerovalent Nickel Atoms
Coordination nickel-bridged fullerene
polymer [{NiĀ(Me<sub>3</sub>P)<sub>2</sub>}Ā(Ī¼-Ī·<sup>2</sup>,Ī·<sup>2</sup>-C<sub>60</sub>)]<sub>ā</sub> (<b>1</b>) has been obtained via reduction of a Ni<sup>II</sup>(Me<sub>3</sub>P)<sub>2</sub>Cl<sub>2</sub> and C<sub>60</sub> mixture. Each nickel
atom is linked in the polymer with two fullerene units by Ī·<sup>2</sup>-type NiāCĀ(C<sub>60</sub>) bonds of 2.087(8)ā2.149(8)
Ć
length. Nickel atoms are coordinated to the 6ā6 bonds
of C<sub>60</sub> as well as two trimethylphosphine ligands to form
a four-coordinated environment around the metal centers. Fullerene
cages approach very close to each other in the polymer with a 9.693(3)
Ć
interfullerene center-to-center distance, and two short interfullerene
CāC contacts of 2.923(7) Ć
length are formed. Polymer
chains are densely packed in a crystal with interfullerene center-to-center
distances between fullerenes from neighboring polymer chains of 9.933(3)
Ć
and multiple interfullerene CĀ·Ā·Ā·C contacts.
As a result, three-dimensional dense fullerene packing is formed in <b>1</b>. According to optical and electron paramagnetic resonance
spectra, fullerenes are neutral in <b>1</b> and nickel atoms
have a zerovalent state with a diamagnetic d<sup>10</sup> electron
configuration. The density functional theory calculations prove the
diamagnetic state of the polymer with a singletātriplet gap
wider than 1.37 eV
Redox Modulation of <i>para</i>-Phenylenediamine by Substituted Nitronyl Nitroxide Groups and Their Spin States
Three kinds of <i>para</i>-phenylenediamine (PDA) derivatives
bearing nitronyl nitroxide (NN) groups were prepared and characterized
on the basis of the electrochemical, electron spin resonance (ESR)
spectroscopic, absorption spectroscopic, and magnetic susceptibility
measurements. It was clarified that the oxidation potential of the
central PDA unit is strongly influenced by the numbers of substituted
electronāwithdrawing NN groups. In addition, the intervalence
charge transfer in the central PDA unit was detected in the monocationic
states of the PDAs with two NN groups, indicating the coexistence
of the localized spins and the delocalized spin on theses molecules.
Moreover, pulsed ESR measurements confirmed that the delocalized spin
on the central PDA unit and the localized two spins on the NN groups
were ferromagnetically coupled in the monocationic states
Magnetic and Optical Properties of Layered (Me<sub>4</sub>P<sup>+</sup>)[M<sup>IV</sup>O(Pc<sup>ā¢3ā</sup>)]<sup>ā¢ā</sup>(TPC)<sub>0.5</sub>Ā·C<sub>6</sub>H<sub>4</sub>Cl<sub>2</sub> Salts (M = Ti and V) Composed of ĻāStacking Dimers of Titanyl and Vanadyl Phthalocyanine Radical Anions
Two isostructural
salts with radical anions of titanyl and vanadyl
phthalocyanines (Me<sub>4</sub>P<sup>+</sup>)Ā[M<sup>IV</sup>OĀ(Pc<sup>ā¢3ā</sup>)]<sup>ā¢ā</sup>Ā(TPC)<sub>0.5</sub>ĀĀ·C<sub>6</sub>H<sub>4</sub>Cl<sub>2</sub> (M
= Ti (<b>1</b>), V (<b>2</b>)), where TPC is triptycene,
were obtained. These salts contain phthalocyanine layers composed
of the {[M<sup>IV</sup>OĀ(Pc<sup>ā¢3ā</sup>)]<sup>ā¢ā</sup>}<sub>2</sub> dimers with strong ĻāĻ intradimer
interaction. The reduction of metal phthalocyanines was centered on
the Pc macrocycles providing the appearance of new bands in the near
infrared range and a blue shift of Q- and Soret bands. That results
in the alternation of shorter and longer CāN<sub>imine</sub> bonds in Pc<sup>ā¢3ā</sup>. Only one <i>S</i> = 1/2 spin is delocalized over Pc<sup>ā¢3ā</sup> in <b>1</b> providing a Ļ<sub>M</sub><i>T</i> value
of 0.364 emu K mol<sup>ā1</sup> at 300 K. Salt <b>1</b> showed antiferromagnetic behavior approximated by the Heisenberg
model for isolated pairs of antiferromagnetically interacting spins
with exchange interaction of <i>J</i>/<i>k</i><sub>B</sub> = ā123.0 K. The Ļ<sub>M</sub><i>T</i> value for <b>2</b> is equal to 0.617 emu K mol<sup>ā1</sup> at 300 K to show the contribution of two <i>S</i> = 1/2
spins localized on V<sup>IV</sup> and delocalized over Pc<sup>ā¢3ā</sup>. Magnetic behavior of <b>2</b> is described by the Heisenberg
model for a four-spin system with strong intermolecular coupling between
Pc<sup>ā¢3ā</sup> in {[V<sup>IV</sup>OĀ(Pc<sup>ā¢3ā</sup>)]<sup>ā¢ā</sup>}<sub>2</sub> (<i>J</i><sub>inter</sub>/<i>k</i><sub>B</sub> = ā105.0 K) and
weaker intramolecular coupling between the V<sup>IV</sup> and Pc<sup>ā¢3ā</sup> (<i>J</i><sub>intra</sub>/<i>k</i><sub>B</sub> = ā15.2 K)
Structural Transitions from Triangular to Square Molecular Arrangements in the Quasi-One-Dimensional Molecular Conductors (DMEDO-TTF)<sub>2</sub>XF<sub>6</sub> (X = P, As, and Sb)
A series of quasi-one-dimensional molecular conductors
(DMEDO-TTF)<sub>2</sub>XF<sub>6</sub> (X = P, As, and Sb), where DMEDO-TTF
is dimethylĀ(ethylenedioxy)Ātetrathiafulvalene,
undergo characteristic structural transitions in the range of 130ā195
K for the PF<sub>6</sub> salt and 222ā242 K for the AsF<sub>6</sub> salt. The dramatic structural transition is induced by the
order of the ethylenedioxy moiety, and the resulting anion rotation
leads to the reconstruction of the HĀ·Ā·Ā·F interaction
between the methyl groups and the anions. The unique hydrogen bonds
play a crucial role in the transition. As a result, the molecular
packing is rearranged entirely; the high-temperature molecular stacks
with an ordinary quasi-triangular molecular network transforms to
a quasi-square-like network, which has never been observed among organic
conductors. Nonetheless, the low-temperature phase exhibits a good
metallic conductivity as well, so the transition is a metalāmetal
(MM) transition. The resistivity measured along the perpendicular
direction to the conducting <i>ac</i>-plane (Ļ<sub>ā„</sub>) and the calculation of the Fermi surface demonstrate
that the high-temperature metal phase is a one-dimensional metal,
whereas the low-temperature metal phase has considerable interchain
interaction. In the SbF<sub>6</sub> salt, a similar structural transition
takes place around 370 K, so that the quasi-square-like lattice is
realized even at room temperature. Despite the largely different MM
transition temperatures, all these salts undergo metalāinsulator
(MI) transitions approximately at the same temperature of 50 K. The
low-temperature insulator phase is nonmagnetic, and the reflectance
spectra suggest the presence of charge disproportionation with small
charge difference (0.14)

Coordination Complexes of Pentamethylcyclopentadienyl Iridium(III) Diiodide with Tin(II) Phthalocyanine and Pentamethylcyclopentadienyl Iridium(II) Halide with Fullerene C<sub>60</sub><sup>ā</sup> Anions
Synthetic
approaches to iridium complexes of metal phthalocyanines
(Pc) and fullerene anions have been developed to give three types
of complexes. The compoundĀ{(Cp*Ir<sup>III</sup>I<sub>2</sub>)ĀSn<sup>II</sup>PcĀ(2ā)}Ā·2C<sub>6</sub>H<sub>4</sub>Cl<sub>2</sub> (<b>1</b>) (Cp* is pentamethylcyclopentadienyl) is the first
crystalline complex of a metal phthalocyanine in which an iridiumĀ(III)
atom is bonded to the central tinĀ(II) atom of Pc via a SnāIr
bond length of 2.58 Ć
. In (TBA<sup>+</sup>)Ā(C<sub>60</sub><sup>ā¢ā</sup>)Ā{(Cp*Ir<sup>III</sup>I<sub>2</sub>)ĀSn<sup>II</sup>PcĀ(2ā)}Ā·0.5C<sub>6</sub>H<sub>14</sub> (<b>2</b>), the {(Cp*Ir<sup>III</sup>I<sub>2</sub>)ĀSn<sup>II</sup>PcĀ(2ā)} units cocrystallize with (TBA<sup>+</sup>)Ā(C<sub>60</sub><sup>ā¢ā</sup>) to form double chains of C<sub>60</sub><sup>ā¢ā</sup> anions and closely packed chains of {(Cp*Ir<sup>III</sup>I<sub>2</sub>)ĀSn<sup>II</sup>PcĀ(2ā)}. Interactions
between the fullerene and phthalocyanine subsystems are realized through
ĻāĻ stacking of the Cp* groups of {(Cp*Ir<sup>III</sup>I<sub>2</sub>)ĀSn<sup>II</sup>PcĀ(2ā)} and the C<sub>60</sub><sup>ā¢ā</sup> pentagons. Furthermore, the spins of
the C<sub>60</sub><sup>ā¢ā</sup> are strongly antiferromagnetically
coupled in the chains with an exchange interaction <i>J</i>/<i>k</i><sub>B</sub> = ā31 K. Anionic (TBA<sup>+</sup>)Ā{(Cp*Ir<sup>II</sup>Cl)Ā(Ī·<sup>2</sup>-C<sub>60</sub><sup>ā</sup>)}Ā·1.34C<sub>6</sub>H<sub>4</sub>Cl<sub>2</sub> (<b>3</b>) and (TBA<sup>+</sup>)Ā{(Cp*Ir<sup>II</sup>I)Ā(Ī·<sup>2</sup>-C<sub>60</sub><sup>ā</sup>)}Ā·1.3C<sub>6</sub>H<sub>4</sub>Cl<sub>2</sub>Ā·0.2C<sub>6</sub>H<sub>14</sub> (<b>4</b>) are the first transition metal complexes containing Ī·<sup>2</sup>-bonded C<sub>60</sub><sup>ā</sup> anions, with the
Cp*Ir<sup>II</sup>Cl and Cp*Ir<sup>II</sup>I units Ī·<sup>2</sup>-coordinated to the 6ā6 bonds of C<sub>60</sub><sup>ā</sup>. Magnetic measurements indicate diamagnetism of the {(Cp*Ir<sup>II</sup>Cl)Ā(Ī·<sup>2</sup>-C<sub>60</sub><sup>ā</sup>)} and {(Cp*Ir<sup>II</sup>I)Ā(Ī·<sup>2</sup>-C<sub>60</sub><sup>ā</sup>)} anions due to the formation of a coordination bond
between two initially paramagnetic Cp*Ir<sup>II</sup>Cl or Cp*Ir<sup>II</sup>I groups and C<sub>60</sub><sup>ā¢ā</sup> units.
DFT calculations support a diamagnetic singlet ground state of <b>4</b>, in which the singletātriplet energy gap is greater
than 0.8 eV. DFT calculations also indicate that the C<sub>60</sub> molecules are negatively charged

Charge and Structural Dynamics in Photoinduced Phase Transition of (EDO-TTF)<sub>2</sub>PF<sub>6</sub> Examined by Picosecond Time-Resolved Vibrational Spectroscopy
Using time-resolved near-infrared reflectance spectroscopy
and
time-resolved mid-infrared vibrational spectroscopy, we studied photoinduced
phase transition of the charge-ordered insulating phase in a charge-transfer
complex (EDO-TTF)<sub>2</sub>PF<sub>6</sub> (EDO-TTF: ethylenedioxy-tetrathiafulvalene)
in the hundred picosecond range after photoexcitation. The temporal
profiles at 0.83ā1.03 eV, which are a characteristic of the
photoinduced charge-disproportionate phase immediately after photoexcitation,
suggested the formation of a new metastable phase in the hundred picosecond
range. Time-resolved vibrational spectra at 1300ā1700 cm<sup>ā1</sup>, where charge- and structure-sensitive Cī»C
stretching vibrational modes are located, elucidated that the nature
of the new phase is very close to that of the high-temperature metallic
phase and it takes about 100 ps for the new phase to emerge accompanied
with charge and structure fluctuation
