Abstract
Dioxido-vanadium(V) complex has been synthesized in good yield, the complex was characterized by IR, UV–visible and 1H NMR spectroscopy. Single crystal X-ray crystallography techniques were used to assign the structure of the complex. Complex crystallized with monoclinic P21/c space group with cell parameters a (Å) = 39.516(5), b (Å) = 6.2571(11), c (Å) = 17.424(2), α (°) = 90, β (°) = 102.668(12) and γ (°) = 90. The hydrazone ligand is coordinate to metal ion in tridentate fashion through –ONO– donor atoms forming a distorted square pyramidal geometry around the metal ion.

Summary
Vanadium is a trace element present which exists in many oxidation states such as V(III), V(IV) and V(V). Among these three, vanadium(V) state has received considerable attention [1,2,3]. Vanadium compounds play a very important role in biochemical as well as in catalytic properties. Several functional model system of vanadium haloperoxidases (VHPOs) compounds containing VO(IV)/VO(V) and/or VO2(V) units derived from O, N, O/S donor ligands have been successfully prepared and their structures have been established with the help of single crystal X-ray crystallography [13,14]. Hydrogen peroxide plays a very important role as reactant both in biological systems and atmospheric chemistry [15]. It is important to develop an effective and convenient method for the detection of hydrogen peroxide
