Synthesis and Characterisation of Polystyrene Supported Chelating Ligands and their Transition and Inner Transition Metal Complexes

Abstract

New polystyrene supported coordination compounds have been synthesized by the reaction of metal salt / metal coordination compound with the polystyrene supported base (PS-LH2)(obtained by the reaction of chloromethylated polystyrene, 3-formylsalicylic acid and ethanolamine). The compounds have the formulae:- PS-TiCl.2DMF, PS-VCl.2DMF, PS-MnCl. 2DMF,PS-FeCl .2DMF,PS-RuCl.2DMF,PS-Ru.3DMF,PS-MoO2.DMF,PS-MoOCl.DMF,PS-UO2.DMF and PS-CoCl.2DMF (DMF=dimethylformamide). The compounds have been characterized by elemental analyses, IR, electronic and magnetic susceptibility measurements. The Ti(III), V(III), Mn(III), Fe(III), Ru(II) and Mo(V) compounds are paramagnetic while Mo(VI) and U(VI) compounds are diamagnetic. The shifts of the (C=N) (azomethine), (C-O) (phenolic) and (C-O) (alcoholic) stretches have been monitored to find out the donor sites of PS-LH2. An octahedral structures for all the compounds have been suggested for the compounds.
