摘要
合成了Ｅｕ（３－ＰＹＡ）３·２Ｈ２Ｏ配合物，通过元素分析和化学分析确定了配合物的组成，测定了标题配合物的激光拉曼光谱．结果表明，标题配合物的羧基具有两种配位方式，分别为双齿和桥式．经与同构配合物Ｓｍ２（３－ＰＹＡ）６·４Ｈ２Ｏ的晶体结构测定结果对照，知标题配合物中有一种Ｅｕ（Ⅲ）格位。
A coordination compound of Eu(3-PYA) 3·2H 2O has been synthesized in this work In Eu(3-PYA) 3·2H 2O Eu stands for Europium,3-PYA is abbreviated from pyridine-3-carboxylic acid group Laser Raman Spectrum and high resolution flourescence spectrum are recorded The results indicate that there is only one slte of Eu(Ⅲ) in Eu(3-PYA) 3·2H 2O The summetry of Eu(Ⅲ) is C 2 The coordination number for the central metal ion is eight
