摘要

Eight new antimony (III) complexes containing dithiocarbamate ligands (R2NCS2)(2)SbBr [R2NCS2 = OC4H8NCS2 (1), C2H5NC4H8NCS2 (2), Me2NCS2 (3), C4H8NCS2 (4)] and (R2NCS2)(3)Sb[R2NCS2 = C5H10NCS2 (5), Bz(2)NCS(2) (6), Et2NCS2 (7), (HOCH2CH2)(2)NCS2 (8)] have been synthesized by the reactions of antimony (111) halides with dithiocarbamate ligands in 1:2 or 1:3 stoichiometries. All the complexes have been characterized by elemental analysis, melting point as well as spectral [IR and NMR (H-1 and C-13)] studies. The crystal structures of complexes 1, 5 and 8 have been determined by X-ray single crystal diffraction, and their electrochemical character has also been studied. The structure of complex 1 shows that the five-coordinated antimony (III) atom adopts a distorted trigonal bipyramidal geometry. Furthermore, the supramolecular structure of 1 consists of a one-dimensional linear molecular chain which is built up by intermolecular Sb... S and S... S weak interactions. In complex 5, the central antimony atom is six-coordinated with a distorted octahedral geometry and the supramolecular structure is constructed by C-H... S weak hydrogen bonds. The structure of complex 8 is stabilized by strong intermolecular hydrogen bonds between the ethanolic hydrogens (O-H). (c) 2007 Elsevier Ltd. All rights reserved.

S和S ... S的弱相互作用建立。在络合物5中，中心锑原子是六配位的，具有扭曲的八面体几何形状，并且超分子结构由C-H ... S弱氢键构成。配合物8的结构通过乙醇氢（O-H）之间的强分子间氢键而稳定。 （c）2007 Elsevier Ltd.保留所有权利。
