Abstract
Two new schiff base complexes, NiL(ClO4)·2H2O (1) and CuL(ClO4)·4H2O (2) {L was condensed from equation molar salicylaldehyde and diethylenetriamine} have been synthesized and characterized. Further, two new bimetallic coordination polymers, {[ML][FeIIFeIII (ox)3] · 1.5H2O}∞ were synthesized and characterized, where ox2- = oxalate, M=Ni2+ (3) or Cu2+ (4). The tested results of elementary analysis of coordination polymers (3) and (4) were according with the theoretical value, and the results of the IR indicated that the coordination of oxalate were bridgetype in compound (3) and (4). 2-D layer coordination polymers were synthesized by oxalate and Fe3+, Fe2+. The result of Mössbauer spectra of (3) and (4) in room temperature revealed that two different postural ferric ions were found in coordination polymer (3) and (4) ,and anions layer was formed by [FeII FeIII (ox)3]- unit. The compounds of (3) and (4) were bimetallic coordination polymers.
