| 摘 要： | 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Na3Eu(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(1H NMR)、碳谱(13CNMR)和氮谱(14N NMR)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.

| Abstract: | 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 Na3Eu(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. |
