The reaction between polystyrene 3-formylsalicylate and 2-Aminobenzylalcohol in DMF in the presence of ethyl acetate results in the formation of polystyrene N-(2-hydroxymethylphenyl)-2'-hydroxybenzylideneimine-3'- carboxylate (I). A benzene suspension of I reacts with mercaptoacetic acid undergoes cyclization and forms polystyrene N-(2-hydroxymethylphenyl)-C-(3'-carboxy-2'-hydroxyphenyl)thiazolidin-4-one, PSCH2–LH2 (II). A DMF suspension of II reacts with Co(II) and MoO2(VI) ions and forms the corresponding polystyrene-anchored coordination compounds, [PSCH2–LHCo(oAc)(DMF)] (III) and [PSCH2–LHMoO2(acac)] (IV). The polystyreneanchored coordination compounds have been characterized on the basis of elemental analyses, spectral (IR, reflectance) studies and magnetic susceptibility measurements. II behave as a monobasic bidentate OS donor ligand in the coordination compounds. The acetato groups in III behave as a monodentate ligand. A square-planar structure for III and an octahedral structure for IV are suggested.
