The first dinuclear zinc(II) dithiocarbarnate complex with butyl substituent groups

The crystal structure of the title compound, bis( -N,N- dibutyldithiocarbamato- 2S:S0)bis[(N,N-dibutyldithiocarba\- forcelb]mato- 2S,S0)zinc(II)], [Zn2(C9H18NS2)4], has been determined at 180 K. The structure contains two crystallographically unique Zn2+ metal centres, showing almost identical slightly distorted tetrahedral coordination environments, and forming a dinuclear complex with two skew-bridging syn-N,N-dibutyldithiocarbamate ligands. Two other dithiocarbamate ligands are connected to the Zn2+ centres in a syn,syn-chelate coordination mode

Aerosol-assisted metallo-organic chemical vapour deposition of Bi2Se3 films using single-molecule precursors: the crystal structure of bismuth(m) dibutyldiselenocarbamate

The complexes [Bi{Se2CN(C2H5)2}3], [Bi{Se2CN(C4H9)2}3], [Bi{Se2CN(CH3)(C4H9)}3] and [Bi{Se2CN(CH3)(C6H13)}3] have been synthesized and characterized structurally using IR, 1H and 13C NMR. In addition, the crystal structure of [Bi{Se2CN(C4H9)2}3] was determined by single-crystal X-ray diffraction, showing the bismuth centre coordinated to three dialkyldiselenocarbamate ligands through the selenium donor atoms. The Bi(III) compounds were used as precursors for the deposition of Bi2Se3 films on glass substrates through aerosol-assisted metallo-organic chemical vapour deposition (AA-MOCVD)

A novel supramolecular organic-inorganic adduct containing alpha-Keggin-type [PW12O40](3-) anions and benzo-15-crown-5 molecules

The structure of the title compound, tris(hydroxonium) 12- phosphato-tetracosa- 2-oxo-dodecaoxododecatungsten hexakis( benzo-15-crown-5)±methanol±water (1/1/1), (H3O)3- [PW12O40] 6C14H20O5 CH3OH H2O (where C14H20O5 is benzo-15-crown-5), has been determined at 180 K. [PW12O40]3ÿ anions are typical of -Keggin structures, and the [H3O (C14H20O5)2]+ sandwich-type moieties contain a large number of short O O close contacts, suggesting strong hydrogen bonding within them

Comprehensive determination of 3JHNHα for unfolded proteins using 13C′-resolved spin-echo difference spectroscopy

An experiment is presented to determine 3JHNHα coupling constants, with significant advantages for applications to unfolded proteins. The determination of coupling constants for the peptide chain using 1D 1H, or 2D and 3D 1H-15N correlation spectroscopy is often hampered by extensive resonance overlap when dealing with flexible, disordered proteins. In the experiment detailed here, the overlap problem is largely circumvented by recording 1H-13C′ correlation spectra, which demonstrate superior resolution for unfolded proteins. J-coupling constants are extracted from the peak intensities in a pair of 2D spin-echo difference experiments, affording rapid acquisition of the coupling data. In an application to the cytoplasmic domain of human neuroligin-3 (hNlg3cyt) data were obtained for 78 residues, compared to 54 coupling constants obtained from a 3D HNHA experiment. The coupling constants suggest that hNlg3cyt is intrinsically disordered, with little propensity for structure

Synthesis and characterisation of a new vanadyl oxalatophosphate compound: (C10H10N2)[(VO)(HPO4)](2)(C2O4)

A new vanadyl oxalatophosphate compound, (C10H10N2)[(VO)(HPO4)]2(C2O4), was synthesized via the hydrothermal approach and characterised structurally using single-crystal X-ray diffraction, FT-IR and thermogravimetric analysis. The compound has twodimensional f½ðVOÞðHPO4Þ 2ðC2O4Þgn 2n anionic layers with C10H10N2 2þ occupying the interlayer spaces

Synthesis, characterisation and magnetic properties of cobalt (II) complexes with 3-hydroxypicolinic acid (HpicOH): [Co(picOH)2(H2O)(2)] and mer-[N(CH3)(4)][Co(picOH)(3)] . H2O

Two complexes with Co2+ and 3-hydroxypicolinic acid, [Co(picOH)2(H2O)2] (I) and mer-[N(CH3)4][Co(picOH)3] Æ H2O (II), have been synthesised and characterised using single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy, and thermoanalytical measurements. The 3-hydroxypicolinate ligands are coordinated to the Co2+ centres via its typical N,O-chelating coordination fashion. While in I the presence of two coordinated water molecules leads to the formation of a neutral [Co(picOH)2(H2O)2] complex which is strongly hydrogen bonded to another four neighbouring complexes, in II the inclusion of a third picOH ligand leads to an anionic octahedral complex, [Co(picOH)3] , in which all the N- and O-atoms are occupying mer positions. The properties of these two compounds were further investigated by measuring their magnetic behaviour
