Abstract:
Two new Schiff base complexes, ZnL(ClO4)·4H2O (A) and CdL(ClO4)·3H2O (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, {[ML][FeIIFeIII(ox)3·H2O]}∞ were synthesized and characterized, in which ox2-=oxalate, M=Zn2+(C) or Cd2+(D). The bonds of νas(C=O), δ(C=O) were at 1635, 818 cm-1 for complex C and 1646, 820 cm-1for complex D, respectively. The results of Mussbauer 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 [FeIIFeIII(ox)3]-unit.

摘要:
合成和表征了两种新的Schiff碱配合物[ZnL(ClO4)@4H2O(A)和CdL(ClO4)@3H2O(B)],其中L=2-{[2-(Aminomethyl-amino)-ethylimino]-methyl}-phenol.A(或B)、FeSO4@7H2O和K3[Fe(ox)3]@3H2O进一步反应,生成了配位聚合物{[ML][FeⅡFeⅢ(ox)3]@H2O}∞,其中M=Zn2+(C)或Cd2+(D).红外光谱和Mossbauer谱测定结果表明,C和D具有二维层状结构,其阴离子层由[FeⅡFeⅢ(ox)3]-单元构成.
