Abstract

A series of rhenium(I) tricarbonyl complexes with bidentate P,O donor ligand o-(diphenylphosphino)benzaldehyde (P∩O) and its Schiff base P,N donor ligand o-[diphenylphosphino)benzylidene]analine (P∩N) have been synthesized and structurally characterized. All the complexes of the type [ReX(CO)(3)(LL)] (where LL = P∩O, P∩N) reveal a distorted octahedral structure with the three carbonyl ligands arranged in the facial fashion.
