摘要
金属有机配合物结构复杂而多样.从零维离散结构、一维链式结构、二维层状结构到三维网络结构,结构变化丰富繁多。近年来,人们在对配合物进行结构研究的同时.对配合物性质的研究与开发也引起了广泛关注翻.在配合物的性能研究中.稀土金属有机配合物的性能研究涉及磁性、催化、荧光等多个领域。大量研究表明.稀土Eu^3+及Tb^3+的配合物具有荧光强度大、选择性高、寿命长等优点,
A europium complex [Eu2(bmd)2(Hbmd)2(H2O)8]·8H2O (H2bmd=Benzimidazole-5,6-dicarboxylic acid) has been synthesized and structurally determined by X-ray diffraction single crystal structure analysis. The crystal belongs to trielinie, space grounp P1, with a=0.754 49 (15) nm, b = 1.253 8 (3) nm, c = 1.405 8 (3) nm, α =71.03 (3)°,β=82.83(3)°, γ=79.12(3)°, V=1.232 1(5) nm^3, Z=1. The complex is a binuclear compound and each Eu(Ⅲ) ion is nine-coordinated. The versatile hydrogen bonds link binuclear units into a three-dimensional (3D) supermoleeular network. Furthermore, the fluorescent properties of the complex have been investigated at room temperature. CCDC: 742510.
