Colorimetric detection of hydrogen peroxide by dioxido-vanadium(V) complex containing hydrazone ligand: synthesis and crystal structure

Dioxidovanadium(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 was used to assign the structure of the complex. Complex crystallized with monoclinic P2/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.
