Formation of thiosemicarbazone-functionalized complexes with (GeS 2) 2 and (SnS 2) 2 units

Abstract

By reaction of organo-functionalized germanium or tin sesquisulfides [(R 1T) 4S 6] (T = Ge, Sn; R 1 = CMe 2CH 2COMe) with thiosemicarbazide or its methyl or phenyl derivative, a series of four compounds were obtained and structurally characterized that are based on an inorganic (TS 2) 2 unit with an extended organic chelate ligand CMe 2CH 2CMeNNCSNHR′ (R′ = H, Me, Ph). The products combine a small, reactive metal chalcogenide moiety with a ligand system that allows for a variety of directed extensions at the terminal NHR′ group. Thus, this work represents the starting point to a multifaceted consecutive chemistry involving both the extension of the binary inorganic unit and further derivatization and/or coordination of the organic ligands.
