Complexes of Ti^IV and Zr^IV with furfuraldazine, 1-thiophenaldazine and 2-pyridinaldazine have been synthesised and characterised on the basis of elemental analysis, molar conductance and ir and uv spectral data. Molar conductance values suggest that the complexes are 1 : 4 electrolytes in 10^-3 M DMF solutions. The ir spectra reflect the Involvement of only three coordination sites of the azine ligands in bonding to metal ions. The formula [ML₂]X₄ (where L=azine ligand; X=CI^- or \(NO_a^-\); ion ; M =metal ion) has been proposed for the complexes.
