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

Abstract

Several 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.
