摘要
通过希土氯化物与L-脯氨酸反应,制得了四种新的希土脯氨酸固体配合物。其通式为:Ln(prol)Cl_3·nH_2O(Ln=Y、La、Sm和Er).用化学分析、电导测定、热重分析、差热分析、红外光谱和核磁共振氢谱,确定了产物的组成,讨论了金属-配体的化学键性质。
Four new solid coordination compounds of rare earth(Ⅲ) wtih L-proline have been prepared by the reaction of rare earth chlorides with L-proline. The general formula of these coordination compounds is Ln(prol)Cl3·nH2O (Ln = Y,La,Sm and Er). The composition of these products has been determined by the methods of chemical analysis, electrical conductivity measurement. The nature of metal-ligand bonding in the compounds was discussed based on IR and H NMR data. Thermal property of these compounds was determined by means of thermogravimetric(TG), and differential thermal analysis(DTA) as well.
