Synthesis and structural characterization of rhenium(I) tricarbonyl complexes with the bidentate ligands o-(diphenylphosphino)benzaldehyde (P O) and o-[(diphenylphosphino)benzylidene]analine (P N)

摘要

A series of rhenium(I) tricarbonyl complexes with bidentate P ,0 donor ligand o-(diphenylphosphino)benzaldehyde (P nO) and its Schiff base P,N donor ligand o-[diphenylphosphino)benzylidene]analine (PnN) have been synthesized and structurally characterized. All the complexes of the type [ReX(CO?)(LL)] (where LL = PnO, PnN) reveal a distorted octahedral structure with the three carbonyl ligands arranged in the fa~jal fashion.
