Synthesis and Structural Characterization of Tris(dimethyldithiocarbamate)Indium(III), InS2CN(CH3)23

摘要

The synthesis and structure of the indium dithiocarbamate, In[SCN(CH3)2]3*1/2 4-mepy (4-mepy = 4-methylpyridine), is described. Indium metal was oxidized by tetramethylthiuramdisulfide in 4-methylpyridine at 25C to form a new, homoleptic indium(HI) dithiocarbamate in yields exceeding 60%. In[S2CN(CH3)213 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 = 12.502 A, alpha= 73.91 (1) degrees, beta = 70.21(1) degrees, gamma = 85.84(1) degrees, Z = 2,v(A(exp 3)) =1057.3(3), R = 0.046, and R(sub w) = 0.061.
