Para- and meta-phenylenbisdithiocarbamate(p- and m-pbdtc) ligands have been synthesized by the reaction of the corresponding phenylenediamines and carbon disulfide in alkaline aqueous solutions. The pbdtc ligands thus obtained were reacted with various di- and triorganotin(IV) compounds to obtain several new organotin-pbdtc complexes. These resultant organotin-pbdtc complexes were isolated and chracterized by means of chemical analysis, IR, MNR and DTA. On the basis of the above results, it is proposed that the product from the reaction of the p-pbdtc ligand with dimethyltin dichloride is a polymeric complex in which the coordination number around the tin atom is six, since the dithiocarbamate moiety acts as bidentate. On the other hand, when m-pbdtc is reacted with diorganotin compounds, monomeric or dimeric complexes are obtained with the coordination number of six and four in dimethyltin-pbdtc and dicyclohexyltin-m-pbdtc complexes, respectively, since the dithiocarbamate moiety acts as bidentate in the former whereas it acts as monodentate in the latter. Unlike the diorganotin-pbdtc complexes, only monomeric form is obtained when triorganotin was reacted with the pbdtc ligands.
