Abstract: Quinoline-8-sulphinic acid (QNSOOH) acts as an ambidentate ligand coordinating through different modes with various transition metal(II) ions. Copper(II) forms a dimer, CU2(QNSOO)2CI2.4H2O,with sulphinato-N, S at pH1 and a monomer, Cu(QNSOO)2.2H2O, with sulphinato-N, O at pH 3. NickeI(II) forms a high spin octahedral sulphinato-N, S complex, while cobaIt(II) forms a low spin octahedral sulphinato-N, S complex. Zinc(II) forms sulphinato-N, O complex and cadmium(II) due to the ‘proximity effect’ forms only sulphinato-O, O complex. All these sulphinato complexes are characterisea with the help of elemental analysis, magnetic moment, conductivity measurement, molecular weight determination, IR and electronic spectra.
