Abstract
New oxidovanadium(V) complexes, [VOL1(bzh))]·H2O (1) and [VOL2(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 (H2L1) and N′-(5-bromo-2-hydroxybenzylidene)-4-methylbenzohydrazide (H2L2), 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. Graphical Abstract
