Abstract

The title complex [{PhS(tBuN)2}(Cl)Ge:→RhCl(cod)] (2) was synthesized by the reaction of three-coordinated chlorogermylene, [PhS(tBuN)2]GeCl (1), supported by a diimidosulfinate ligand with a half equivalent of [RhCl(cod)]2 in benzene. The molecular structure of 2 was determined by 1H and 13C NMR spectroscopies and single-crystal X-ray diffraction (SCXRD) analysis. The electronic property of germylene 1 was assessed by determining the Tolman electronic parameter of the corresponding cis-dicarbonyl Rh(I) complex, [{PhS(tBuN)2}(Cl)Ge:→RhCl(CO)2] (3), that was prepared by the treatment of 2 with carbon monoxide.
