|Title:||Syntheses and characterization of copper(II), nickel(II), iron(III), zinc(II), cadmium(II), zirconium(IV), molybdenum(V and VI) and uranium(VI) complexes of polystyrene supported resin containing the schiff base derived from 3-formylsalicylic acid and o-aminophenol|

|Abstract:||A new series of polystyrene supported metal complexes of the formulae PS - LCu DMF, PS -LNi·3DMF, PS - LFeCl·2DMF, PS - LZn·DMF, PS - LCd·DMF, PS - LMoOCl· DMF, PS -LMoO2·DMF, PS - LZr(OH)2·2DMF and PS - LUO2·DMF (where PS - L=deprotonated polymer- anchored Schiff base) have been synthtesized by the reaction of metal salt/metal complex with the chelating resin containing the schiff base derived from 3-formylsalicylic acid and o-aminophenol. The polymer supported metal complexes have been characterized by elemental analysis, IR, electronic and ESR spectra and magnetic susceptibility measurements. The geometry of the complexes are comparable with the corresponding metal complexes of non-anchored ligand. The polymer supported Cu(II) complex is square planar, Zn(II) and Cd(II) complexes are tetrahedral, Ni(II), Fe(III),U(VI) and Mo(V and VI) complexes are octahedral and zirconium (IV) complex is pentagonal bipyramidal. The polymer-anchored Ni(II), Cu(II), and Mo(V) complexes are paramagnetic while the Zn(II), Cd(II), Zr(IV), U(VI) and Mo(VI) complexes are diamagnetic.|
