The crosslinked chloromethylated polystyrene (PSCH2-Cl) reacts with the Schiff base, derived from condensation of PSCH2-Cl with 3-formylsalicylic acid and salicylhydrazide to form a polystyrene-anchored Schiff base, PSCH2-LH3 (1). Compound 1 reacts with a number of metal ions to form polystyrene-anchored coordination compounds, PSCH2-LHM·DMF (where M = Cu, Zn, Cd, UO2, and MoO2), PSCH2-LHM′ = 3DMF (where M′ = Mn, Co, and Ni), PSCH2-LHFeCl·2DMF, and PSCH2-LHZr(OH) 2·2DMF. The polystyrene-anchored coordination compounds have been characterized by elemental analyses, spectra (infrared, reflectance, and electron spin resonance) and magnetic susceptibility measurements. The polystyrene-anchored compounds are magnetically dilute. Shifts in band positions of the groups involved in coordination have been utilized to find tridentate ONO donor behavior of 1. The polystyrene-anchored Zn(II), Cd(II), Zr(IV), MoO2(VI), and UO2(VI) compounds are diamagnetic, while Mn(II), Co(II), Ni(II), Cu(II), and Fe(III) compounds are paramagnetic. The polystyrene-anchored Cu(II) compound is square planar; Zn(II) and Cd(II) compounds are tetrahedral; Co(II), Ni(II), Mn(II), Fe(III), MoO2(VI), and UO2(VI) compounds are octahedral; and Zr(IV) compound is pentagonal bipyramidal.
