Schiff base complexes of rhenium(IV) and rhenium(V)

Abstract

The interaction of various Schiff bases, LH₂, with trichloro-oxobits (triphenylphosphine) rhenium(V), tetrachlorobis(triphenylphosphine) ruthenium(IV), and other rhenium complexes has given rise to complexes of the following types: (a) Re^V₂O₃L₂ that have a linear ORe–O–ReO system which quadridentate ligands on each rhenium; (b) Re^VOCIL that appear to be octahedral with trans ORe–Cl groups; (c) Re^IVCl₂L that are octahedral with trans chlorines; (d) complexes that have neutral Schiff bases, LH₂ bound to the metal.
