Synthesis, characterization and crystal structure of a novel tetranuclear oxidovanadium(V) complex derived from N'-(2-hydroxy-3-methoxybenzylidene)isonicotinohydrazide with catalytic property

A novel tetranuclear oxidovanadium(V) complex, [V4O4(OEt)(4)L-4], where L is the dianionic form of N'-(2-hydroxy-3-methoxybenzylidene)isonicotinohydrazide (H2L), has been prepared and characterized by physico-chemical methods and single crystal X-ray diffraction. The V atom in the complex is coordinated by the phenolate oxygen, imino nitrogen and enolate oxygen of one aroylhydrazone ligand, one pyridine nitrogen of another aroylhydrazone ligand, one deprotonated ethanol oxygen, and one oxo group, forming an octahedral coordination. The oxidation of olefins with the complex as the catalyst was evaluated, which indicated that the complex has effective catalytic efficiency in the oxidation of several aliphatic and aromatic substrates by using tert-butyl hydrogen peroxide as oxidant.
