Abstract: | Homobimetallic vanadium(V) complex of the composition [(CH3)2NH2+]2[(VO2)2(sloxCl)].4H2O was synthesized from the reaction of V2O5 with bis(5‐chlorosalicylaldehyde)oxaloyldihydrazone ligand in a 1:1 molar ratio in methanol. The structure of the complex was established by X‐ray crystallography. Reactivity of the complex with H2O2 leads to bis (monooxidoperoxidovanadate(V)) [{VO(O2)}2(sloxCl)]2? formation and with HCl, oxidohydroxido complex of composition [(VO (OH)(sloxCl)]2? was formed. Binding interaction of the complex was also investigated toward protein (BSA) and it was found to be 2.21 x 108 M?1. The catalytic activity of the complex in the oxidation of alcohols and oxidative bromination of some organic substrates was also studied, and it showed a great potent as a catalyst. |
