摘要
合成了红色荧光配合物Eu(NO3)3(Phen)2并测定了其晶体结构.配合物属单斜晶系,Cc(#7)空间群.晶胞参数为:a=1.1161(2)nm,b=1.7963(4)nm,c=1.3042(3)nm,α=90.00(0)°,β=100.57(3)°,γ=90.00(0)°.晶胞体积V=2.5704(9)nm3,Z=4.晶体密度Dc=1.805g·cm-3.最终的偏离因子R=0.0293.中心Eu3+离子为10配位,配位原子分别为3个NO3-根的6个氧原子和2个中性螯合配体Phen的4个氮原子,构成高度畸变的双冠四方反棱柱体,或双冠四边形顶蝶形底扭棱柱体.
The red lurninescent complex Eu(NO3)3(Phen)2(Phen: 1,10-phenanthroline) was synthesized, its crystal structure was measured. The complex crystallizes in monoclinic, space group Cc ( #7). The cell dimensions are a=1. 116 1(2) nm, b=1. 796 3(4) nm, c=1. 304 2(3) nm, α=90. 00(0)°, β=100.57(3)°,γ=90.00(0)°, V=2.5704(9) nm^3, Z=4 and Dc=-1. 805 g·cm^-3. The final R is 0.029 3. Each Eu^3+ ion is ten coordinated by six oxygen atoms of three NO7 anions and four nitrogen atorns of two Phen molecules, resulting in seriously distorted bicapped square antiprism, or bicapped square top-butter-fly-shape bottom twisted prism.
