Abstract
The reaction of the complex trans-ReOCl3(PPh3)2 with potentially bidentate N,O-donor benzimidazolyl-alcoholate ligands (HL) in the presence of triethylamine in ethanol and benzene produces the complexes ReO(OEt)(L)2 and ReOCl(L)2, respectively. These compounds were characterized by elemental analysis, NMR, vibrational and optical spectroscopy. Mechanisms for the formation reactions and probable configurations of the complexes are proposed, and these are supported by qualitative and spectroscopic studies.Keywords
