邻啡啰啉─吡啶2，6二甲酸铕二、三元配合物的NMR研究

NMR STUDIES OF BINARY AND TERNARY COMPLEXES FOR Eu WITH 1,10-PHENANTHROLINE AND PYRIDINE-2,6-DICARBOXYLIC ACID

报道了稀上铕（Ｅｕ３＋）与吡啶－２，６－二甲酸（Ｈ２ＤＰＣ）及邻啡啉（Ｐｈｅｎ）形成的二元和三元固体配合物的制备．对它们进行了元素分析，确定该配合物的组成为二元Ｎａ３［Ｅｕ（ＤＰＣ）３］２Ｈ２Ｏ和三元ＮａＥｕ（ＤＰＣ）２·４Ｈ２Ｏ，对上述配合物的结构作了核磁共振氢谱（１ＨＮＭＲ）、碳谱（１３ＣＮＭＲ）和氮谱（１４ＮＮＭＲ）及红外光谱（ＩＲ）的研究．吡啶－２，６－二甲酸中的羧基以单齿配位（整个分子为三齿配位）．二、三元配合物中铕的配位数分别为９和８．

The preparation for binary and ternary solid complexes of rare earth Eu3+ with pyridine-2,6-dicarboxylic acid(H2DPC) and 1,10 - Phenanthroline are reported in this article. Their compositions confrmed by elemental analysis, being binary Na3[Eu(DPC)3]2H2O and ternary NaEu(DPC)2. Phen. 4H2O. Their structures were studied by 1H. 13C. 14N N-MR and ER spectra. The pyridine-2,6-dicarboxylic acid is a tridentate ligand. Two coordination numbers of europium are nine and eight in binary and ternary complexes respectively.
