摘要
合成了铜-钠混合金属配位聚合物[(CuL)2(CH3OO)Na(H2O)4]2(简写为1)并进行了元素分析和单晶X射线衍射分析,L为{2-(2′-酚基)-Δ2-噻唑-4-羧酸}。晶体结构分析表明配合物形成Cu4Na2的六核混合金属大环。相邻的Cu4Na2环之间通过进一步的配位作用连结成包含更大的Cu8Na4大环的二维网状结构。该晶体属于三斜晶系P墿空间群,晶胞参数分别为:a=1.0777(4)nm,b=1.5221(6)nm,c=1.6994(6)nm,α=84.58(1)°,β=76.31(1)°,γ=89.97(1)°,V=2.696(2)nm3,Z=2,Mr=1447.26,dc=1.783 g.cm-3,T=293(2)K,μ=1.816 mm-1,F(000)=1472,R1=0.0794,wR2=0.1819[I>2σ(I)].
A novel copper （ Ⅱ ）-sodium （Ⅰ ） mixed-metal coordination polymer [ （ CuL ） 2 （ CH3OO ） Na （H2O）4]2 （abbreviated as 1 ）has been synthesized and characterized by elemental analysis and single- , -A-thlazohne-4-carboxyhc acid. Crystal crystal X-ray diffraction where H2L = 2- （ 2-hydroxyphenyl ） -Δ2- -thiazoline-4-carboxylic acid. Crystal structure analysis reveals that 1 has an impendent symmetry unit consisted by two slightly different half of the Cu4Na2 six-nuclear molecular rings. Furthermore, the Cu4Na2 rings connect further with each other to form a two-dimensional network containing larger Cus Na4 rings. Crystal data： triclinic, space group Pi with a = 1.0777（4） nm, b = 1.5221（6） nm, c = 1.6994（6） nm, α = 84.58（1）°,β = 76.31（1） °, γ = 89.97（1）°, V = 2.696 （2） nm3, Z = 2, Mr = 1447.26, dc = 1.783 g·cm-3 , T = 293（2） K, =1.816 mm-1 F（000） = 1472 R1= 0.0794, wR2= 0.1819 [I〉2σ（I） ]
