Synthesis and Structural Characterization of Tris(dimethyldithicarbamate)Indium(III), In[S2CN(CH3)2]3

The synthesis and structure of the indium dithiocarbamate, In[S2CN(CH3)2]30 central dot 1/2 4- mepy (4-mepy = 4-methylpyridine), is described. Indium metal was oxidized by tetramethylthiuramdisulfide in 4-methylpyridine at 25 C to form a new, homoleptic indium(III) dithiocarbamate in yields exceeding 60%. In[S2CN(CH3)2]3 exists as a discrete molecule with a distorted-octahedral geometry. The compound crystallizes in the P 1-bar (No. 2) space group with a = 9.282(l) A, b = 10.081 (1) A, c, c = 12.502 A, alpha = 73.91 (1)(sup 0), beta = 70.21(1)(sup 0), gamma = 85.84(1)(sup 0), Z = 2, V (A(sup 3) = 1057.3(3), R = 0.046, and R(sub w) = 0.061.
