Synthesis and structural characterization of tris(dimethyldithiocarbamate) indium(III), In[S2CN(CH3)2]3

The synthesis and structure of the indium dithiocarbamate, In[S2CN(CH3)(2)](3) . (1/2) 4-mepy (4-mepy = 4-methylpyridine), is described. Indium metal was oxidized by tetramethylthiuram disulfide in 4-methylpyridine at 25 degreesC 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) over bar (No. 2) space group with a = 9.282(1) Angstrom, b = 10.081(1) Angstrom, c = 12.502 Angstrom, alpha = 73.91(1)degrees, beta = 70.21(1)degrees, gamma = 85.84(1)degrees, Z = 2, V(Angstrom) = 1057.3(3), R = 0.046 and R-w = 0.061.
