Novel Dioxo Complexes of Molybdenum(VI) with the ONS Donors - Pyridoxal Thiosemicarbazone Ligands

Pyridoxal thiosemicarbazone complexes are of a great interest because of their antiviral, antitumor and antibacterial properties.New polymeric dioxomolybdenum(VI) polynuclear complexes [MoO2L1a]n, [MoO2L1b]n, [MoO2L2a]n and [MoO2L2b]n and monomeric complexes [MoO2L1b(CH3OH)], [MoO2L2a(CH3OH)] and [MoO2L2b(CH3OH)] were prepared by the reactions of [MoO2(C5H7O2)2] and appropriate pyridoxal thiosemicarbazone ligand (where H2L1a is pyridoxal 4-methylthiosemicarbazone hydrochloride, H2L1b is pyridoxal 4- methylthiosemicarbazone, H2L2a is pyridoxal 4- phenylthiosemicarbazone hydrochloride and H2L2b is pyridoxal 4-phenylthiosemicarbazone) in dry acetonitrile, dry methanol or combination of both solvents. In all complexes the ligands are coordinated to molybdenum as the ONS donors through phenolic oxygen, imine nitrogen and thiol sulphur, while the sixth coordination site around molybdenum in monomeric complexes is completed by the methanol molecule. All complexes were characterised by means of chemical analysis, IR spectroscopy, TG measurements and one and two-dimensional NMR. Complexes [MoO2L2a(CH3OH)] and [MoO2L2b(CH3OH)] were also characterised by X-ray crystallography. Ligands were characterised by DSC measurements and by one and two-dimensional NMR.
