Synthesis and characterization of hydrophilic hydroxy-pyridinones and their complexes with molybdenum(VI)

Abstract

We have prepared four N -substituted hydroxypyridinones containing alcohol and morpholine groups. Complexes of the type cis -MoO2L2, where L represents the hydroxypyridinonato ligands have also been synthesized. The ethanolamine derivative, cis -MoO2(hep)2 (5), has been characterized by an X-ray diffraction study whereby the pyridinone ligands are bound to molybdenum in a cis bidentate fashion via the deprotonated hydroxy groups and the ketone moieties. Crystals of (5) are triclinic, with a 9.1930(7), b 14.2718(8), c 14.6219(9) Å, a 106.816(5), ß 95.902(5), ? 96.350(5)°, Z 4, space group P –1.
