摘要
研究了萘并15冠5与CdCl_2·2.5H_2O,KSCN的反应,得到标题配合物[K(N15C5)_2]_2[Cd(SCN)_4]CH_2Cl_2,并通过元素分析、红外光谱、X—射线单晶衍射对配合物进行了表征.配合物为单斜晶系,空间群P^(-1),晶体学数据:a=15.521(2)(?)、b=15.617(3)(?)、c=20.582(3)(?),α=73.528(3)°、β=80.355(3)°、γ=61.295(2)°,V=4 193.6(12)(?)~3,Z=4,D_(calcd)=1.411Mg/m^3,F(000)=1 848,R1=0.057 9,wR2=0.122 7,R1=0.175 7,wR2=0.1708.标题配合物由两个[K(N15C5)_2]^+配阳离子和一个[Cd(SCN)_4]^(2-)配阴离子组成.两个N15C5分子和钾离子通过10个K-O键形成夹心式配位结构,[Cd(SCN)_4]^(2-)中的Cd^(2+)与四个NCS基团中的四个N配位,形成变形四面体结构.配阳离子[K(N15C5)_2]^+与配阴离子[Cd(SCN)_4]^(2-)通过静电作用形成中性配合物.
The reactions of CdCl2 · 2.5H2O,KSCN with N15C5 was studied and the title complex [K （N15C5）2]2[Cd（NCS）4 wes obtained. The title complex [K（N15CS）2]2[Cd（NCS）4] wes characterized by the melting point determination, IR and the the X-ray diffraction analysis. The title complex belongs to triclinic system, the space group P-1. Unit cell dimension：a=15.521（2）A、b=15.617（3）A、c=20.582（3）A,α=73.528（3）°、β=80.355（3）°、γ-61.295（2）°,V=4193.6（12）A3,Z=4,Dcaled=1.411Mg/m3,F（000）=1848,R1=0.0579,wR2=0.1227,R1=0.1757,wR2=0.1708. The title complex consists of two [K（N15C5）2]~ complex cations and one [Cd（NCS）4]2- complex anion. In the complex cation [K （N15C5）2]＋ ,K＋ is coordinated by ten O atoms of two N15C5 forming sandwich structure,For the [Cd （NCS）4]2- complex anion, the Cd is coordinated by four N atoms with the coordination geometry of deformation tetrahedron structure.
