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

The 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. © 2013 king saud university.
