Mixed ligand complexes of the general type [Cd2(dtc)4(4,4_-bipy)] (dtc = diethyldithiocarbamate or piperidinedithiocarbamate anions; 4,4'-bipy = 4,4'-bipyridine) have been synthesized and characterized. IR spectra of the complexes show that the thioureide ni(C-N) bands are observed at lower frequency than the values obtained for the parent dithiocarbamates. Charge transfer transitions are observed in the region 310-340 nm. Thermogravimetric studies show that the 4,4'-bipyridine adducts are more stable than the 2,2'-analogues. Also, the crystal structure of the benzene solvate of [Cd(pipdtc)2]2 (pipdtc = piperidinedithiocarbamate anion) is reported. The coordination geometry can be described as a distorted trigonal bipyramid around each cadmium
