在甲醇体系中合成了镉配合物[Cd(L)2(H2O)2](ClO4)2·MeOH(1)[L=1,3,5-三(3-吡啶基甲氧基)苯]。通过元素分析及X-射线单晶衍射对其进行了表征。结构分析结果表明该化合物属于三斜晶系,P1^-空间群,晶胞参数为a=1.0571(5)nm,b=1.0590(5)nm,c=1.2708(7)nm,α=87.460(16)°,β=81.895(17)°,γ=62.326(14)°,晶胞体积V=1.2470(11)nm^3,Z=1,Dcalc=1.569g·cm^-3,F(000)=604,μ=6.26cm^-1,R=0.0352,wR=O.0664。在化合物1中,每个Cd(Ⅱ)的配位环境为变形八面体,而每个配体L通过其两个吡啶基团连接2个Cd(Ⅱ)形成一维链状结构,并进一步通过O-H…N,O-H…O和C—H…O氢键作用形成了一个具有三维结构的超分子化合物。
The complex [Cd(L)2(H2O)2](ClO4)2·MeOH (1) [L=1,3,5-tris(3-pyridylmethoxy)benzene] was synthesized in methanol and characterized by elemental analysis and X-ray crystallography. The results of structural analysis indicate that the complex crystallizes in the triclinic, space group P1^- with a=1.0571(5) nm, b=1.059 0(5) nm, c= 1.2708(7) nm, α=87.460(16)°, β=81.895(17)°, γ=62.326(14)°, V=1.247 0(11) nm^3, Z=1, Dcalc=1.569 g.cm^-3, F(000) =604,μ=6.26 cm^-1, the final R=0.035 2 and wR=0.0664. The coordination environment of Cd(Ⅱ) is a distorted octahedron, and each L ligand links two Cd(Ⅱ) atoms using two of three pyridyl groups to generate an one-dimensional (1D) chain structure. The 1D chains are further connected by O-H…N, O-H…O and C-H…O hydrogen bonds to give a three-dimensional structure. CCDC: 283825.
