Abstract
The behavior of thiosalicylic acid (H(2)TSA) and 6-mercaptopurine (MP) with vanadyl(IV) cation has been studied in solution at different ligand-to-met al 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 enviro nment of V in (I) is consistent with S and O atoms of TSA and two hydroxy b ridges between two metal centers. Thr nearest neighbor atoms to V in (II) a re S and N provided by the ligand and O atoms from hydroxyl groups. These r esults have been supported by physicochemical studies.
