Synthesis, characterization and single crystal X-ray analysis of chlorobis(N,N-dimethyldithiocarbamato-S,S′)antimony(III)

AbstractThe title compound chlorobis(N,N-dimethyldithiocarbamato-S,S′)antimony(III) has been prepared in distilled acetonitrile and characterized by physicochemical [melting point and molecular weight determination, elemental analysis (C, H, N, S & Sb)], spectral [FT–IR, far IR, NMR (1H & 13C)] studies. The crystal and molecular structure was further confirmed using single crystal X-ray diffraction analysis which features a five-coordinate geometry for antimony(III) within a ClS4 donor set. The distortion in the co-planarity of ClSbS3 evidences the stereochemical influence exerts by the lone pair of electrons on antimony(III). Two centrosymmetrically related molecule held together via C–H···Cl secondary interaction result in molecular aggregation of the compound
