Syntheses and characterization of doubly-bidentate bis(carboxyamide) complexes of oxomolybdenum(IV)

Summary Complexes of oxomolybdenum(IV) with doubly-bidentate bis(carboxyamide) ligands, derived by condensing benzidine (Bd) or p-phenylenediamine (PPD) with phthalic anhydride (PAH) and succinic anhydride (SAH), have been synthesized by phosphine oxo abstraction from dioxomolybdenum(VI) complexes via ligand displacement. The structures of the complexes were determined by elemental analyses, i.r. and electronic spectral data, cyclic voltammetry and thermal analysis.
