CHARACTERIZATION OF AN UNUSUAL REACTION-PRODUCT OF TIN(II) CHLORIDE WITH SODIUM N,N-DIETHYLDITHIOCARBAMATE

The reaction of sodium N,N-diethyldithiocarbamate trihydrate with tin( II) chloride under aerobic conditions yields the unexpected cis-dichlo robis(N,N-diethyldithiocarbamato)tin(IV) which has been characterized by X-ray crystallography. This illustrates the tin to be in a distorte d octahedral configuration; the coordination valencies being provided by the two chlorines in cis positions and two dithiocarbamates in cis- orientations. The Sn-119 NMR of the complex is consistent with the pre sence of six coordinated tin(IV). The formation of the complex is expl ained via the intermediate product, tetraethylthiuram disulphide.
