摘要
标题配合物晶体属三斜晶系,P1空间群,晶胞参数a=10792(2)nm,b=11896(2)nm,c=12446nm,α=10512(3)°,β=9376(3)°,γ=11319(3)°,V=1392(1)nm-3,Z=2,Dx=1659g·cm-3。配合物晶体由双核分子组成,两个中心Eu3+通过羧基桥联,它们的化学环境相同。Eu3+的配位数为8,其配位多面体为一畸变的四方反棱柱体。在77K配合物的荧光光谱说明配合物中仅存在一种Eu3+格位。
The title complex Eu(BA)3phen(BA: benzoate, phen: 1,10phenanthroline) crystallizes in triclinic, P1 space group with cell parameters as follows: a=10792(2) nm, b=11896(2) nm, c=12446(3) nm, α=10512(3)°, β=9376(3)°, γ=11319(3)°, Z=2, Dx=1659 g·cm-3. The crystal is composed of a dinuclear molecule. Two europium ions are bridged with the carboxylato groups, they are in the same chemical environment. Coordination number of the central europium ion is eight and its coordination polyhedron is a distorted square antiprism. The luminescence spectra of the complex recorded at 77 K indicate one Eu3+ site only.
