摘要
合成了开链冠醚:2,6-二(8’-喹啉氧甲基)吡啶,并研究了其与CdCl2·2.5H2O的配位反应,得到标题配合物:[Cd(C25H19N3O2)H2O](μ-Cl)[Cd(C25H19N3O2)Cl][CdCl4],并通过熔点、红外光谱、X-射线单晶衍射进行了表征.标题配合物由两个配阳离子[ClCd(C25H19N3)]+,[ClCd(C25H19N3)H2O]+和一个配阴离子[CdCl4]2-组成,两个配阳离子中,中心离子Cd2+除与开链冠醚中的N、O原子配位之外,还分别与Cl-、H2O配位,配位几何构型均为变形五角双锥.两个配阳离子之间通过Cl桥键相连.配阳离子与配阴离子之间通过静电作用形成中性分子.
The open chain crown ether：2,6-bis（8′-quinoylyloxymethyl）pyridine was synthesized and the title complex：[Cd（C25H19N3O2）H2O]（μ-Cl）[Cd（C25H19N3O2）Cl][CdCl4] was obtained by the reaction of the 2,6-bis（8′-quinoylyloxymethyl）pyridine with CdCl2 · 2. 5H2O. The title complex wes characterized by the melting point determination, IR and the the X-ray diffraction analysis. The title complex belongs to monoelinic system, the space group P2（1）/n. Unit cell dimension： a = 14. 181（8）A.b = 14.726（8） .A、c = 27. 234（14）A, β = 98.704（9） °, V =5 621（5）,A^3, Z = 4, Dcalcd= 1. 601 Mg/
m^3, F（000） = 2 672, R1 = 0. 107 2,ωR2 =0. 233 9, R1 = 0. 292 0, ωR2 =0. 345 7. The title complex is made up of two [ClCd（C25 H19 N3）]^＋ , [ClCd（C25 H19 N3 ）H2O]^＋ complex cations and one [Cd Cl4]^2-complex anion. In each of the two complex cations： [ClCd（C25 H19N3）]^＋ and [ClCd（C25 H19N3）H2O]^＋The ed was coordinated by the N, O atoms of the open chain ether and the H2O or the Cl^- with the coordination geomitry of distorted pentagonal bipyramid, and forthermore linked by the bridged interactions of Cl^-.
