Synthesis, spectroscopic studies and crystal structures of ReI(CO)3(NN)Cl complexes with N,Næ-bis(substituted benzylidene)ethane-1,2-diamine Schiff base ligands

Abstract

Four new Re(I) tricarbonyl-diimine complexes were prepared by reaction of Re(CO)5Cl with N,Næ-bis(substituted benzylidene)ethane-1,2-diamine Schiff base ligands. These compounds were characterized by physico-chemical methods, and their crystal structures were established by X-ray diffraction. The coordination geometry at the Re atom is that of a distorted octahedron, with three carbonyl ligands in the facial geometry. © 2009 Springer Science+Business Media B.V.
