Facies analysis of the Jito Formation ( Upper Triassic Nariwa Group ) in Jito Area, Kawakami, Okayama Pref., SWJapan.
Facies analysis and analysis of stratigraphy together with folded structure of the Norian Jito Formation were studied in Jito Area, Kawakami, Okayama Pref., SW Japan. Results of regional mapping and measured sections reconstruct three-dimensionally distribution of the Jito Formation. The Jito Formation is sub-divided into the four new members; the Shimohira Muddy Sandstone Member, the Otofuji Coarse-grained Turbidite Member, the Misawa Fine-grained Turbidaite Member, and the Ide Conglomerate Sandstone Member in ascending order. The shimohira Muddy Sandstone Member is interpreted to be deposited in an inner-bay. The Otofuji Coarse-grained Turbidite Member and The Misawa Fine-grained Turbidite Member are considered to be deposited on a continental shelf. The Ide Conglomerate Sandstone Member is inferred to be a shallow marine deposit. As a result, the Jito Formation is regarded as one transgressive-regressive package
N-(1,10-Phenanthrolin-5-yl)-4-(2-pyridyl)benzamide monohydrate
In the title molecule, C24H16N4O·H2O, the benzene ring of the 1,10-phenanthroline group and that of the 2-phenylpyridine group are respectively twisted by 67.9 (1) and 15.3 (3)° from the carbamoyl group defined by the plane of the O=C—N group of atoms. The water molecule is hydrogen bonded to one of the phenanthroline N atoms. In the crystal structure, significant π–π stacking interactions occur, with centroid-to-centroid separations in the range 3.567–3.681 (2) Å
Dibromido(2,3,9,10-tetramethyl-1,4,8,11-tetraazacyclotetradeca-1,3,8,10-tetraene)cobalt(III) bromide
In the title compound, [CoBr2(C14H24N4)]·Br, the CoIII ion is located on an inversion centre and possesses a distorted octahedral coordination geometry in which four nitrogen donors of the ligand molecule are in the equatorial plane and two Br− ions occupy both the axial sites to give a trans isomer. The Br- counter- anion is also located on an inversion centre
Chlorido(dimethyl sulfoxide-κS)[2-(2-pyridyl)phenyl-κ2 N,C 1]platinum(II)
In the title compound, [Pt(C11H8N)Cl(C2H6OS)], the S atom of dimethyl sulfoxide is trans to the pyridyl N atom [Pt—S = 2.2181 (11) Å] and the chlorido ligand is trans to the carbon donor of 2-(2-pyridyl)phenyl [Pt—Cl = 2.4202 (10) Å]. The [2-(2-pyridyl)phenyl]platinum(II) unit forms a one-dimensional stack along the c axis with two independent interplanar separations of 3.44 (9) and 3.50 (2) Å
4-[(3-Formyl-4-hydroxyphenyl)diazenyl]-N-(pyrimidin-2-yl)benzenesulfonamide
The title molecule, C17H13N5O4S, has a trans configuration with respect to the diazenyl (azo) group. The pyrimidine ring and the terminal benzene ring are inclined at angles of 89.38 (4) and 1.6 (6)°, respectively, with respect to the central benzene ring. The conformation of the molecule is in part stabilized by an intramolecular O—H⋯O hydrogen bond. In the crystal structure, molecules related through inversion centers form hydrogen-bonded dimers involving the sulfonamide N—H group and the N atom of the pyrimidine ring
Bis(2,2′-bipyridine){ethyl 4′-[N-(4-carbamoylphenyl)carbamoyl]-2,2′-bipyridine-4-carboxylate}ruthenium(II) bis[hexafluoridophosphate(V)]
In the title compound, [Ru(C10H8N2)2(C21H18N4O4)](PF6)2, the RuII complex cation reveals a slightly distorted octahedral coordination. The coordination bonds of the 4,4′-substituted bipyridyl donors [Ru—N = 2.038 (3) and 2.051 (3) Å] are shorter than those of the 2,2′-bipyridyl donors [Ru—N1 = 2.065 (3)–2.077 (3) Å], due to the electron-withdrawing effects of the substituents at the 4,4′-positions. The angles between the pyridyl planes of the three bipyridyl ligands are 1.5 (2), 6.3 (3) and 8.7 (2)°, respectively. The cations are connected by anions via N—H⋯F interactions
Bis(triethylammonium) bis(μ-pyrazine-2,3-dithiolato)bis(pyrazine-2,3-dithiolato)diferrate(III) methanol disolvate
In the title compound, (C6H16N)2[Fe2(C4H2N2S2)4]·2CH4O, the [FeIII(pdt)2]− anion (pdt is pyrazine-2,3-dithiolate) forms a centrosymmetric dimer supported by two FeIII—S bonds [Fe—S = 2.4787 (4) Å]. In the crystal structure, dimers form a one-dimensional stack along the b axis via π–π stacking interactions, the interplanar separation between adjacent dimers being 3.51 (2) Å. The methanol solvent molecule is involved in two hydrogen bonds in which the hydroxyl group acts as a hydrogen-bond donor to the N atom of a pdt ligand and the O atom acts as an acceptor for the NH group of the triethylammonium cation
Diaqua(1,4,7,10,13-pentaoxacyclopentadecane)iron(II) bis(μ-cis-1,2-dicyano-1,2-ethylenedithiolato)bis[(cis-1,2-dicyano-1,2-ethylenedithiolato)ferrate(III)] 1,4,7,10,13-pentaoxacyclopentadecane disolvate
The title compound, [Fe(C10H20O5)(H2O)2][Fe2(C4N2S2)4]·2C10H20O5, consists of an [FeII(15-crown-5)(H2O)2]2+ cation, sandwiched between and O—H⋯O hydrogen bonded by two additional 15-crown-5 ether molecules and two independent [FeIII(mnt)2]− anions, where 15-crown-5 ether denotes 1,4,7,10,13-pentaoxacyclopentadecane and mnt denotes cis-1,2-dicyano-1,2-ethylenedithiolate. Each independent [FeIII(mnt)2]− unit forms a centrosymmetric dimer supported by two intermonomer FeIII—S bonds [Fe—S = 2.4715 (9) and 2.4452 (9) Å]. In the crystal structure, the dimers form one-dimensional π–π stacks along the a axis, with an interplanar separation of 3.38 (6) Å
1-[4-(Diaminomethyleneaminosulfonyl)phenyliminiomethyl]-2-naphtholate N,N-dimethylformamide disolvate
The asymmetric unit the title compound, C18H16N4O3S·2C3H7NO, contains a molecule in a zwitterionic form with a deprotonated hydroxyl group and an iminium group, and two dimethylformamide solvent molecules. The dihedral angles of the guanidine group and the naphthyl ring system with respect to the central benzene ring are 76.04 (7) and 3.45 (9)°, respectively. The conformation of the molecule may be influenced, in part, by two intramolecular hydrogen bonds, while in the crystal structure, intermolecular hydrogen bonds form one-dimensional chains along [010]
