Synthesis, crystal structure, and urease inhibition of [N′-(3,5-dibromo-2-hydroxybenzylidene)isonicotinohydrazido]-(benzohydroxamato)oxovanadium(V)
摘要:
A new oxovanadium(V) complex [VOL(BZH)] was prepared by the reaction of [VO(Acac)(2)] (Acac = acetylacetonate) with N'-(3,5-dibromo-2-hydroxybenzylidene)isonicotinohydrazide (H2L) and benzohydroxamic acid (HBZH) in methanol. Crystal and molecular structure of the complex was determined by elemental analysis, infrared spectra and single crystal X-ray diffraction. The complex crystallizes in the monoclinic space group P2(1)/c, with unit cell dimensions a = 11.424(1), b = 12.012(1), c = 19.565(2) , beta = 93.487(3)A degrees, V = 2679.8(4) (3), Z = 4, GOOF = 1.152, R (1) = 0.0593, and wR (2) = 0.1942. The V atom is in octahedral coordination. Thermal stability and the inhibition of urease of the complex were studied.
