DITHIOCARBAMATES OF DIMETHYLTHALLIUM(III) - CRYSTAL-STRUCTURE OF DIMETHYL(DI-N-PROPYLDITHIOCARBAMATO)THALLIUM(III)

Six solid compounds of composition [TlMe2(dtc)] (where dtc is a dithio carbamate anion) have been obtained. [TlMe2(S2CNnPr2)] Crystallizes in the space group C2 with a = 19.672(2), b = 8.5698(5), c = 9.194(2) an gstrom, beta = 116.02(1)-degrees and Z = 4. The thallium atom is coord inated to the two sulfur atoms of a slightly anisobidentate dithiocarb amate ligand and to the two methyl groups, which form a highly distort ed tetrahedral environment. In the crystal lattice these units are lin ked by additional weak Tl...S interactions. The main coordination char acteristics of this compound seem to be common to the other complexes prepared, both in the solid state and in solution in CDCl3 or DMSO-d6, to judge by their spectral (IR and NMR) properties.
