Synthesis and characterization of polystyrene supported coordination compounds of dibasic tridentate Schiff base

2494-2499Several polystyrene supported coordination compounds of the types, PSCH2- LM.DMF (M=Cu, Zn, Cd, MoO2 and UO2) PSCH2- LFeCl.2DMF, PSCH2- LZr(OH)2.2DMF and PSCH2- LM.3DMF (M=Mn, Co and Ni) have been synthesized and characterized by elemental analyses, IR , reflectance, ESR spectral and magnetic susceptibility measurements. The Mn(II), Fe(III), Co(II), Ni(II), MoO2(VI) and UO2 (VI) compounds have an octahedral structure, Cu(II) compound is square planar, Zn(II) and Cd(II) compounds are tetrahedral, while Zr(IV) compound is pentagonal-bipyramidal. The compounds, PSCH2- LM.3DMF (M=Mn, Co and Ni), PSCH2- LFeCl.2DMF and PSCH2 –Lcu.DMF are paramagnetic, while PSCH2-LM.DMF(M=Cd, MoO2, Zn and UO2) and PSCH2- LZr(OH)2.2DM F are diamagnetic. PSCH2- LH2 behaves as tridentate (ONO donor) dibasic in these compounds. The structures of the compounds are comparable with the corresponding coordination compounds of the non anchored Schiff base
