摘要 采用改进的固相Wittig反应,合成了一种新型的具有电子给受体和π共轭结构的咪唑衍生物1-{反式4-[4-(N,N-二乙基氨基)苯乙烯基]苯}咪唑(C21H23N3,简作L).室温下,将L与Co(SCN)2在甲醇中反应,合成了配合物Co(SCN)2(C21H23N3)4.X射线单晶衍射分析结果表明,该晶体属于三斜晶系,P1空间群,晶胞参数a=0.9317(3)nm,b=1.2753(4)nm,c=1.6691(5)nm,α=89.521(5)°,β=84.591(5)°,γ=80.052(5)°,V=1.9446(11)nm3,Z=1,μ=0.329mm-1,Dc=1.234Mg/m3,F(000)=765,R1=0.0601,wR=0.1381,GOF=1.030,中心原子Co(Ⅱ)的配位数为6,分别与来自4个L的咪唑N及2个SCN-的N配位,形成八面体的空间构型.配合物分子通过非典型氢键和π-π堆积作用形成三维超分子结构.研究结果表明,配合物具有很好的光学性质. A novel imidazole derivative with π-conjugated system, 1- [ trans-4- (4-diethylaminostyryl) phenyl ] imidazole(L) and its complex, CoL4 (SCN)2, were prepared. The structure of the complex was determined by single crystal X-ray diffraction analysis. The crystal is of orthorhombic system, space group P1^- with a = 0.9317(3) nm, b=1.275 3(4) nm, c=1.669 1(5) nm, α=89.521(5)°, β=84.591(5)°, γ= 80. 052(5)°, V= 1. 944 6( 11 ) nm^3, Z = 1, μ =0.329 mm^-1, Dc = 1. 234 Mg/m^3, F(000) =765, R1 = 0. 060 1, wR = 0. 138 1, GOF = 1. 030. In the molecular structure of Co(SCN) 2L4, Co^Ⅱ atom is six coordinated by four N atoms of the ligands(L) and two N atoms of thiocyanate to form an octahedral geometry. The untypical hydrogen bonds and π-π stacking interaction lead to three-dimensional supramolecular formation. The optical properties were experimentally studied.
