Syntheses, spectroscopic and magnetic properties of polystyrene-anchored coordination compounds of thiazolidinone

D. Kumar, A. Kumar, D. Dass


The reaction between polystyrene 3-formylsalicylate and furoic acid hydrazide in DMF in the presence of ethyl acetate results in the formation of polystyrene N-(2-carbamoylfuranyl)-3'-carboxy-2'-hydroxybenzylideneimine (I). A benzene suspension of I reacts with mercaptoacetic acid and forms the polystyrene N-(2-carbamoylfuranyl)-C-(3'-carboxy-2'-hydroxyphenyl)thiazolidin-4-one, PSCH2–LH2 (II). A DMF suspension of II reacts with Mn(II), Ni(II), Cd(II), Fe(III) and UO2(VI) ions and forms the polystyrene-anchored coordination compounds of the types, [PSCH2–LMn(DMF)3], [PSCH2–LNi(DMF)3], [PSCH2–LCd(DMF)], [PSCH2–LH2FeCl3] and [PSCH2–LHUO2(NO3)(DMF)]. The polystyrene-anchored coordination compounds have been characterized on the basis of elemental analyses, spectral (IR, reflectance) studies and magnetic susceptibility measurements. II acts as a neutral tridentate ONO donor ligand in [PSCH2–LH2FeCl3], a monobasic tridentate ONO donor ligand in [PSCH2–LHUO2(NO3)(DMF)], a dibasic tridentate ONO donor ligand in [PSCH2–LMn(DMF)3], [PSCH2–LNi(DMF)3] and [PSCH2–LCd(DMF)]. A tetrahedral structure for Cd(II) and an octahedral structure for Mn(II), Ni(II), Fe(III) and a square-antiprism geometry for UO2(VI) complex are suggested.
