Two new Schiff base complexes, ZnL(ClO 4)·4H 2O (A) and CdL(ClO 4)·3H 2O (B), where L=2 {\[2 (Aminomethyl amino) ethylimino\] methyl} phenol, have been synthesized and characterized by elemental analysis and infrared spectra. Further, two new bimetallic coordination polymers, {\\[Fe II Fe III (ox) 3·H 2O\]} ∞ were synthesized and characterized, in which ox 2- =oxalate, M=Zn 2+ (C) or Cd 2+ (D). The bonds of ν as (C=O), δ(C=O) were at 1635, 818 cm -1 for complex C and 1646, 820 cm -1 for complex D, respectively. The results of Mssbauer spectra of C and D revealed that there exist two kinds of valence ions. The two bimetallic coordination polymers feature the 2 D layer structure in the solid state, and their anions layer was formed by the \[Fe II Fe III (ox) 3\] - unit.
