چکیده

Nickel(ii) complexes of pyrrolidinedithiocarbamate (pdtc) having the general formula,[ni(pdtc)2],[ni(pdtc)cl]n,k[ni(pdtc)(cn)2] and [ni(pdtc)(cys)] (cys = cysteine) have been prepared and characterized by ir spectroscopy and thermal analysis (tga and dta). the results of thermal analysis are consistent with the proposed composition of the complexes. it has been observed that the ligands i-,scn- and thiolates (except cysteine) are replaced on addition of pdtc leading to the formation of [ni(pdtc)cl]n. the ir data suggest that coordination of the pyrrolidinedithiocarbamate (pdtc) takes place through the two sulfur atoms in a symmetrical bidentate fashion. single crystal analysis of the expected [ni(pdtc)2] crystals showed that the product was nis,rather than a pdtc complex.
