Abstract

The complexes of antimony(III) and bismuth(III) with piperidine (Pipdtc), morpholine (Morphdtc) and thiomorpholinedithiocarbamate (Timdtc) of general formula Sb2-(Rdtc)3X3 and M(Rdtc)X2 (M is antimony or bismuth, X a halogen and Rdtc the dithiocarbamates) have been prepared and characterized by spectroscopic methods. The IR spectra suggest that the dithiocarbamate group coordinates as a bidentate ligand; the metal-sulphur and metal-halide stretching modes have also been assigned. The spectral data are discussed and compared with those of the corresponding trisdithiocarbamate and monohalobisdithiocarbamate derivatives. The molecular weight determinations indicate that all these dithiocarbamate complexes are dimeric. Tentative stereochemistries are proposed and discussed on the basis of the results obtained.
