• Resumen

  • Aminomethylated polystyrene (PSCH2-NH2) reacts with 3-ethoxysalicylaldehyde in equimolar amounts to produce monobasic bidentate (ON donor) polystyrene-anchored Schiff base (PS-LH). The latter upon refluxing with metal the ions in 1:2 molar ratios gives polystyrene-anchored coordination compounds of types: [PSCH2-LM(OAc)(DMF)] (where M = Cd, Co, Cu, Zn, UO2), [PSCH2-LNi(OAc)(DMF)3], [PSCH2-LFeCl2(DMF)2], [PSCH2-LMCl(CH3OH)] (where M = Cd, Zn) and [PSCH2-LMoO2(acac)]. The polystyrene-anchored compounds have been characterized on the basis of elemental analyses, spectral (IR, reflectance, ESR) and magnetic susceptibility measurements. The polystyrene-anchored Co(II), Cu(II), Ni(II) and Fe(III) compounds are paramagnetic, while others are diamagnetic. Co(II) and Cu(II) compounds are square-planar; Zn(II) and Cd(II) compounds are tetrahedral; Ni(II), Fe(III), MoO2(VI) and UO2(VI) compounds are octahedral.
