铕与对甲基苯甲酸及2，2＇－联吡啶三元配合物的谱学研究

Study on Spectroscopy Ternary Complex of Europium with P-Methylbenzoate Acid and 2,2'-Dipyridine

元素分析表明稀土铕（Ｅｕ^（３＋））与对甲基苯甲酸（Ｐ－ＭＢＡ）及２．２＇－联吡啶（ｄｉｐｙ）形成的三元配合物的组成为Ｅｕ_２（Ｐ－ＭＢＡ）_６（ｄｉｐｙ）_２，对甲基苯甲酸、２，２＇－联吡啶均以双齿配位，中心铕离子的配位数为８，两个铕离子通过四个对甲基苯甲酸基桥联，形成双核配合物，对该配合物的结构作了核磁共振氢谱、碳谱及红外光谱的研究。

The composition for ternary complex of rare earth europium with P-methylbenzoate acid and 2,2'-dipyridine confirmed by elemental analysis ,is Eu_2 (P-MBA)_6 (dipy)_2. Both P-methylbenzoate acid and 2, 2'-dipyridine were bidentate ligands. The coordination number of the center europium ion are eight. Two europiums were bridge-linked by four P-methylbenzoates. Forming a binuclear complex.The structure of this complex was studied by ￣1H,￣(13)C NMR and IR spectroscopy.
