New oxorhenium complexes with 2-(diphenylphosphanyl)-N-(2-thioethyl)benzamide (HPNS) and trimethyl-, triethyl- and triphenyl-hydroxyl silylated monodentate thiols are reported. These new complexes have been prepared by reacting [(NBu4)-Bu-n][Re(O)Cl-4] with the tridentate HPNS and the corresponding silylated thiol at room temperature. The characterization of the complexes involved elemental analysis, P-31 and H-1 NMR spectroscopies and X-ray crystallographic analysis for the triethyl-silylated Re complex.
