A Vanadyl Complex Bearing an ONO Isonicotinohydrazone Ligand: XRD, Spectroscopy, and Catalytic Sulfoxidation

A new vanadium complex was prepared by reacting [vo(acac)2] with an ono isonicotinohydrazone ligand. various techniques including uv-vis, ft-ir, chn, and sc-xrd were utilized to characterize the synthesized complex. the data collected from the diffraction study showed that the vanadium ion is hexacoordinated and has a distorted octahedral geometry. the vv ion is coordinated to o,n,o donor sites of the liagnd and a methoxide o atom in the equatorial positions, while methanolic and oxo o atoms occupy the axial sites. moreover, the catalytic activity of the vanadium complex was studied in the sulfoxidation reaction of different sulfides using hydrogen peroxide.
