The reaction of phenoxo-functionalised imidazolium L+Cl-(L= [HO-4,6-di-lBu-C6H2-2-CH | CHCfrjNCHCHN) ( ] ) with anhydrous EuCL, in a 2:1 and 3 :1 molar ratio in THF gives the same complex L2+[ EuCl5 ]2- · THF. The complex has been characterized by IR spectrum, single-crystal X-ray diffraction. The data of the crystal structure indicates the complex belong to mon-oclim,space group P21/c with a = 0.96664(8)nmMr = 1060. 30 ,Z- 4, Dc = 1. 221 Mg/m3,μ( MoKα) = 1. 36 mm-1, F(000 ) = 2200. The title complex is composed of an anion [EuCl5(THF) ]2- and two cations[HO-4,6-di-'Bu-C6H2-2-CH2]CH(iPrNCHCHN) ) ]2+ to form an web structure by the interconnection of anions and cations via hydrogen-bonding. The central metal Eu in the anionic unit coordinated to five Clatoms and one oxygen atom from solvated THF molecule to form a six-coordinated distorted octahedron geometry.%芳氧功能化咪唑盐L+ Cl-(L=HO-4,6-di-tBu-C6H2-2-CH2{ CH[ iPrNCHCHN]})与无水EuCl3分别按照摩尔比为1:2和1:3反应成功合成相同芳氧功能化咪唑基五氯化铕L2+[EuCl5(THF)]2-,产物通过元素分析、IR、X-ray射线衍射表征.晶体结构数据表明此配合物属于单斜晶体,空间群P21/c,晶胞参数a=0.96664(8) nm,b=1.63312(12) nm,c=3.6850(3) nm,β=97.600(2)°,V=5.7662(8) nm3,Mr=1060.30,Z=4,Dc=1.221 Mg/m3,μ(MoKα)=1.36 mm-1,F(000)=2200.目标化合物是由阴离子[EuCl5 (THF)]2-和[HO-4,6-di-tBu-C6H2-2-CH2{ CH(iPrNCHCHN)｝ ]2+通过氢键作用而形成的空间网状结构的晶体,阴离子中中心金属(Eu)是由五个氯原子以及来自THF的氧原子形成扭曲八面体的构型.
