| Abstract: | Abstract The behavior of thiosalicylic acid (H2TSA) and 6-mercaptopurine (MP) with vanadyl(IV) cation has been studied in solution at different ligand-to-metal ratios and pH values. The preparation and characterization of VO/TSA(I) and VO/MP(II) complexes in the solid state is reported. The chemical environment of V in (I) is consistent with S and O atoms of TSA and two hydroxy bridges between two metal centers. The nearest neighbor atoms to V in (II) are S and N provided by the ligand and O atoms from hydroxyl groups. These results have been supported by physicochemical studies. |
