Five-coordinate Bromobis(dialkyldithiocarbamate) Complexes of Arsenic, Antimony, and Bismuth

Abstract

Fifteen bromobis(dialkyldithiocarbamate) complexes of arsenic, antimony, and bismuth have been prepared by reacting the corresponding tris(dialkyldithiocarbamates) with bromine. The structure of these compounds is studied by i.r., n.m.r., and electronic spectra. From the interpretation of the spectroscopic data it is deduced that each dithiocarbamate group acts as a bidentate ligand. The spectral data are discussed and compared to those of the corresponding tris(dialkyldithiocarbamate) complexes.
