【摘要】 合成和表征了一种新的Schiff碱配合物MnL(ClO4)·3H2 O(1) (其中L为n(水杨醛 )∶n(二乙撑三胺 ) =1∶1缩合而成的Schiff碱 )。 1与FeSO4·7H2 O和K3 [Fe(ox) 3 ]·3H2 O(ox =oxalate)进一步反应 ,生成了双金属层状配位聚合物 { [MnL][FeⅡFeⅢ(ox) 3 ]·1.5H2 O} ∞(2 )。IR和M¨ossbauer谱测定结果表明 ,2具有二维层状结构 ,其阴离子层由 [FeⅡFeⅢ(ox) 3 ]-单元构成。变温磁化率 (5K～ 10 0K)测试结果表明 ,2中的自旋载体之间存在反铁磁交换作用。 5K时的磁滞现象表明 2在低温时可能存在铁磁有序 ,这可能是亚铁磁或自旋倾斜造成的更多还原

【Abstract】 A new Schiff base complex MnL(ClO 4)·3H 2O (1) (L represents a condensed schiff base from equation molar salicylaldehyde and diethylenetriamine) was synthesized and characterized. Further, a new coordination polymer {[Fe ⅡFe Ⅲ(ox) 3]·1.5H 2O} ∞(2)(ox=oxalate) was synthesized and characterized. The results of IR and Mssbauer spectra of 2 revealed that the coordination polymer exists 2 D layer structure in the solid state, and the anion layer is formed by [Fe ⅡFe Ⅲ(ox) 3] unit. The magnetic properties of 2 have been measured and the results indicate that there is magnetic ordering in the low temperature, which may arise from intermolecular ferromagnetic interactions or spin canted effects.更多还原
