In addition, some of them may be used as analytical reagents for the dete rmination of trace elements. In this work, we report the synthesis and characterization of (E) -1-((2-amino-51 nitrophenyliminio)methylnaphthalene-2-olate. This ligand was synthesized and characterized by FTIR, H 13 and C NMR, and single crystal X-ray crystallography. The single crystal XRD result show that the compound is zwitterionic and exists in a trans configuration about the C=N bond. INO-P12 SYNTHESIS AND STRUCTURAL STUDY OF OXIDOVANADIUM(IV) AND OXIDOVANADIUM(V) COMPLEXES Wong Hon Wee and Lo Kong Mun Department of Chemistry, Faculty of Science, University of Malaya, Kuala Lumpur 50603, Malaysia E-mail: [email protected] Six new oxyvanadium(V) complexes were prepared from the reactions of vanadyl sulfate with Schiff base ligands derived from substituted pyruvic acid and substituted benzoic acid hydrazide [X CH2(COOH)C=NNHCOC6H4Y, X = H, CH3; Y = H, Cl, Br, NO2 and NH3]. The resulting vanadium(V) complexes were obtained as a resulting of oxidation of the oxovanadium(IV) ion. The complexes were characterized by IR and NMR spectroscopies. The molecular structures of the complexes were determined by single crystal X-ray crystallography. The vanadium(V) atom in the resulting complexes were found to be N,Ochelated by the benzohydrazidate anion a nd O,N,O’-chelated by the 2-(ben...
