Gallium and indium dithiocarboxylates: Synthesis, spectroscopic characterization and structure of [MeGa(S2Ctol)2]

Add time:08/11/2019    Source:sciencedirect.com

Several gallium and indium dithiocarboxylate complexes of the type [MenM(S2CR)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,13C{1H}) spectroscopy. Structure of [MeGa(S2Ctol)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 [Me2InS2Ctol] underwent a two-step thermal decomposition leading to the formation of tetragonal β-In2S3.
