Crystal Structure and Properties of Ternary Europium Complex Eu(NO3)3(phen)2

摘要/Abstract

摘要:

通过X射线单晶衍射测试了配合物Eu(NO3)3(phen)2的晶体结构(phen=1,10-邻菲啉).该配合物以单核分子形式存在,中心离子Eu(Ⅲ)分别与硝酸根上的氧原子和1,10-邻菲啉上的氮原子以双齿螯合方式配位,配位数为10.荧光光谱表明该配合物有Eu(Ⅲ)的特征发射光谱,其中5D07F2(615nm)跃迁发射强度最高.该配合物具有良好的热稳定性.

Abstract:

A europium ternary complex Eu(NO3)3(phen)2( phen=1,10-phenanthroline) has been sy nthesized and it's structure has been determined by single-crystal X-ray diff raction.The title complex is mononuclear molecule.The cent ral Eu(Ⅲ) ion is connected with sixox ygen atoms of three nitrate anions and with four nit rogen atoms of two1,10-phenanthroline molecules through the mode of chelating bidentate.The coordination number of the center Eu(Ⅲ) ion is ten.Luminescence spectra of the title complex indicate that the emission peak of 615nm is the most intensive.Thermal decomposition indicates that the complex has fine thermal stability.
