Synthesis, characterization and crystal structures of oxovanadium(V) complexes with benzohydrazone and 8-hydroxyquinoline
Two new oxovanadium(V) complexes, [VOL1 (HQ)] (1) and [VOL2(HQ)] (2), were prepared by the reaction of [VO(acac)2] (where acac = acetylacetonate), 8-hydroxyquinoline (HHQ) with N?-(5-fluoro-2-hydroxybenzylidene)-4-fluorobenzohydrazide (H2L1) and N?-(5-fluoro-2-hydroxybenzylidene)-4-methoxybenzohydrazide (H2 L2 ), respectively, in methanol. Crystal and molecular structures of the complexes were determined by elemental analysis, infrared and UV-visible spectra and single crystal X-ray diffraction. Complex 1 crystallizes in the orthorhombic space group Pbcn, with unit cell dimensions a = 32.327(2) A, b = 8.189(2) A, c = 16.817(1) A, V = 4451.9(9) A3, Z = 8, GOOF = 1.060, R1 = 0.0587 and wR2 = 0.0921. Complex 2 crystallizes in the monoclinic space group P21/n, with unit cell dimensions a = 12.4965(8) A, b = 13.3795(9) A, c = 13.8324(9) A, beta = 115.555(2), V = 2086.5(2) A3, Z = 4, GOOF = 1.047, R1 = 0.0378 and wR2 = 0.0919. The V atoms in the complexes are in octahedral coordination, with the phenolate oxygen, imino nitrogen and enolate oxygen of the benzohydrazone ligand and the hydroxy oxygen of 8-hydroxyquinoline in the equatorial plane and with the pyridine nitrogen of 8-hydroxyquinoline and one oxo group in the two axial positions. Thermal stability of the complexes was also studied.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: catalyst-ligand, you can also check out more blogs about3153-26-2
