Group IV Metal Complexes of the Dithiocarbamate Ligahd Derived from Propanediamine

Fropanediamine dithiocarbamate and its metal complexes with MCl4. (Si = M Ge, Sn, Ti, and Zr) and Ph2-SnCl2 have been synthesized and characterized. The results indicate that MCI4. reacts in a 1, 4 (metal : dithiocarbamate) ratio yielding an octahedral compound with two symmetrically and two unsym-metrically bound dithiocarbamato groups while Ph2SnCl2 reacts in a 1: 1 ratio leading to the formation of a stable five-coordinate complex with the phenyl groups occupying the equatorial positions.
