Homobimetallic vanadium(V) complex of the composition [(CH 3 ) 2 NH 2 + ] 2 [(VO 2 ) 2 (sloxCl)].4H 2 O was synthesized from the reaction of V 2 O 5 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 H 2 O 2 leads to bis (monooxidoperoxidovanadate(V)) [{VO(O 2 )} 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 10 8 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.
