Bimetallic Coordination Polymers {[FeⅡFeⅢ(ox)3]·1.5H2O}∞ with Layer Structure Syntheses, Spectra Characterization
【摘要】 合成和表征了两种新的Schiff碱配合物 [NiL(ClO4 )·3H2 O (1)和CuL(ClO4 )·4H2 O (2 ) ,其中L是由摩尔比为 1∶1的水杨醛和二乙撑三胺缩合而成的Schiff碱。 1(或 2 )、FeSO4 ·7H2 O和K3 [Fe(ox) 3 ]·3H2 O进一步反应 ,生成了双金属层状配位聚合物 { [ML][FeⅡFeⅢ(ox) 3 ]·1 5H2 O} ∞ ,其中M2 + =Ni2 + (3)或Cu2 +(4 )。红外光谱和M ssbauer谱测定结果表明 ,3和 4具有二维层状结构 ,其阴离子层由 [FeⅡFeⅢ(ox) 3 ]-单元构成
【Abstract】 Two new schiff base complexes, NiL(ClO 4)·3H 2O (1) and CuL(ClO 4)·4H 2O (2) {L was condensed from equation molar salicylaldehyde and diethylenetriamine} have been synthesized and characterized. Further, two new bimetallic coordination polymers, {[Fe ⅡFe Ⅲ(ox) 3]·1.5H 2O} ∞ were synthesized and characterized, where ox 2-= oxalate, M=Ni 2+ (3) or Cu 2+ (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 Fe 3+,Fe 2+.The result of M*issbauer 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 [Fe ⅡFe Ⅲ(ox) 3] - unit.The compounds of (3) and (4) were bimetallic coordination polymers.
