## Abstract

Several gallium and indium dithiocarboxylate complexes of the type $[Me_nM(S_2CR)_{3-n}]$ (M = Ga, In; n = 0, 1, 2; R = phenyl (Ph),p-tolyl (tol), mesityl (Mes)) have been synthesized. These complexes were characterized by elemental analysis, IR, UV–vis and NMR $(^1H,^{13}C\{^1H\})$ spectroscopy. Structure of $[MeGa(S_2Ctol)_2]$ was established by X-ray crystallography. The gallium atom adopts a distorted five coordinate geometry which is intermediate between trigonal bipyramidal and square pyramidal configurations. The complex $[Me_2InS_2Ctol]$ underwent a two-step thermal decomposition leading to the formation of tetragonal $\beta-In_2S_3$.
