The complexes of Ti(III), oxovanadium(IV), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), and Hg(II) with gallacetophenone phenylhydrazone (GAPPH) have been synthesized and characterised by analytical, conductivity, thermal, magnetic, infrared, electronic and ESR data.All the complexes have 1:2 (metal:ligand) stoichiometry.All the complexes are non-electrolytes in dimethylformamide, except Ti(III) complex which is 1:1 electrolyte.The infrared spectral data of the metal complexes indicate that GAPPH acts as a mononegative bidentate ligand coordinating through oxygen of o-hydroxy group and nitrogen of azomethine group.The electronic spectral data suggest that Ti(III) and Fe(II) complexes are octahedral, oxovanadium(IV) complex is tetragonal and Ni(II) and Cu(II) complexes are square-planar.The Co(II), Zn(II) and Hg(II) complexes are tetrahedral.
