Syntheses, characterization, and urease inhibition of oxidovanadium(V) complexes with tridentate hydrazone and bidentate benzohydroxamate ligands

New oxidovanadium(V) complexes, [VOL 1 (bzh))]·H 2 O (1) and [VOL 2 (bzh))] (2), were prepared by the reaction of [VO(acac) 2 ] (where acac = acetylacetonate) and benzohydroxamic acid (Hbzh) with N′-(5-bromo-2-hydroxybenzylidene)-3-methylbenzohydrazide (H 2 L 1 ) and N′-(5-bromo-2-hydroxybenzylidene...

Description
Summary:New oxidovanadium(V) complexes, [VOL 1 (bzh))]·H 2 O (1) and [VOL 2 (bzh))] (2), were prepared by the reaction of [VO(acac) 2 ] (where acac = acetylacetonate) and benzohydroxamic acid (Hbzh) with N′-(5-bromo-2-hydroxybenzylidene)-3-methylbenzohydrazide (H 2 L 1 ) and N′-(5-bromo-2-hydroxybenzylidene)-4-methylbenzohydrazide (H 2 L 2 ), respectively, in methanol. Structures of the complexes were determined by elemental analysis, infrared and UV-vis spectra. Single crystal structures of the complexes were determined by X-ray diffraction. Vanadiums have octahedral coordination. Thermal stability and the inhibition of urease of the complexes were studied.
