| Abstract: | Two new vanadyl(IV) complexes with s-triazine based ligands, 4-hydroxy,2,6,bis
(hydrazino)-s-triazine and 4-hydroxy-2,6-bis(hydroxyamino)-s-triazine were synthesized
and characterized by elemental analysis, electronic, FTIR, 1H NMR, 13C NMR
spectroscopy. In addition magnetic susceptibility, cyclic voltammetry, conductivity
measurement, melting point determination and vanadium and sulphate estimation were also
undertaken. Elemental analysis and IR data revealed bi-dentate nature of the ligand and
participation of SO4
2- in coordination of the VO(II)-HBHATZ complex. The nonelectrolytic
nature of complexes was ascertained from conductivity measurements UV-Vis
and magnetic susceptibility measurements indicate a square pyramidal geometry of the
complex. |
