Abstract
The reaction of [VO(acac)2] with 3-methyl-N′-[1-(2-hydroxynaphthyl)ethylidene]benzohydrazide (H2L1) and 3-methyl-N′-[(2-hydroxy-1-naphthyl)methylidene]benzohydrazide (H2L2), respectively, in methanol affords two new oxovanadium(V) complexes, [VO(OMe)L1]2 (1) and [VO(OMe)(HOMe)L2] (2). Both complexes have been characterized by elemental analysis, I.R., and single crystal X-ray diffraction methods. Complex (1) is a methoxide-bridged dinuclear oxovanadium(V) compound, while complex (2) is a mononuclear oxovanadium(V) compound. The dinegative hydrazone ligands coordinate to the metal atoms through phenolate, imine, and deprotonated amine donor atoms. The geometry around each vanadium atom is a distorted VNO5 octahedron in both complexes.
