Synthesis and structure of some triphenyltin(IV) dithiocarbamate compounds

Abstract

A low temperature synthesis is described for the preparation of organotin dithiocarbamate compounds (including N-cyclic and N-monosubstituted derivatives) in which the products have low levels of the usual sulfide impurities. IR spectra cannot differentiate unambiguously the bidentate and anisobidentate modes of bonding of the dithiocarbamate ligands with the metal, but 1H NMR spectra of the (C 6H 5) 3Sn moiety exhibit ( o-mp) shift differences which can, in part, be attributed to anisobidentate bonding. The effect of solvents on shift values is also indicative of this unsymmetric chelation.
