Several new polystyrene-anchored coordination compounds of the types [PSCH₂-LMn.3DMF], [PSCH₂-LFeC1.2DMF], [PSCH₂-LCo. 3DMF], [PSCH₂-LCu.DMF], [PSCH₂-LZn.DMF], [PSCH₂-LZr(OH)₂.2DMF], [PSCH₂-LMoO₂.DMI], [PSCH₂- LCd.DMF] and [PSCH₂-LUO₂.DMF] (where, PSCH₂-LH₂ is polystyrene-anchored dibasic tridentate Schiff base obtained from the condensation of 3-formylsalicylic acid and 4-amino-5-inercapto-3-methyl-1,2,4-triazole) have been synthesized by the reaction of metal salt/metal coordination compound with PSCH₂-LH₂. The Mn^II, Fe^III, Co^II, Ni^ll and Cu^ll compounds are paramagnetic while Zn^IV, Zr^IV, Mo^VI, Cd^II and U^VI compounds are diamagnetic. The Cu^ll compound is square-planar, Zn^Il and Cd^II compounds are tetrahedral, Fe^III, Co^II, Ni^II, Mo^VI and U^VI compounds are octahedral, and Zr^IV compound is pentagonal bipyramidal.
