邻菲罗啉、己二酸和硝酸铜在水溶液中反应得到一种新颖的四核铜配合物[Cu4(phen)4(NO3)2(H2O)2-(adip)4/4(Hadip)4/2](NO3)2·2H2O(其中H2adip=己二酸),并经元素分析,IR,UV,TG和X射线单晶衍射分析表征.该配合物晶体属三斜晶系,P1空间群,a=1.0146(2)nm,b=1.0261(2)nm,c=1.8285(4)nm,α=91.66(3)°,β=92.19(3)°,γ=112.76(3)°,V=1.7520(6)nm3,Z=1,Dc=1.639g/cm3,C66H66Cu4N12O28,Mr=1729.47,F(000)=886,μ=1.294mm-1,R1和wR2分别为0.0447和0.1141.己二酸根通过4个羧基O将两个U形双核亚单元联接成具有一个对称中心的双U形四核结构,其中每个U型亚单元包含晶体学上不对称的2个Cu(Ⅱ)原子.每个Cu(Ⅱ)离子均处于畸变的四方锥配位环境,除与己二酸氢根(Hadip)、己二酸根(adip)和邻菲罗啉(Phen)的N,O配位形成锥底平面外,其中的1个Cu(Ⅱ)与水配位,而另一个Cu(Ⅱ)则与硝酸根配位.配合物晶体结构中存在着广泛的氢键和π…π作用.
A novel tetranuclear copper complex [Cu 4 (phen) 4 (NO 3) 2 (H 2 O) 2 (adip) 4/4 (Hadip) 4 was synthesized by the reaction of phenanthroline, adipic acid and copper nitrate in aqueous solution / 2] (NO3) 2 · 2H2O (H2adip = adipic acid), and characterized by elemental analysis, IR, UV, TG and X-ray single crystal diffraction analysis.The complex crystal is a triclinic system, P1 space group , a = 1.0146 (2) nm, b = 1.0261 (2) nm, c = 1.8285 (4) nm and α = 91.66 (3) °, β = 92.19 (3) ° and γ = 112.76 = 1.7520 (6) nm3, Z = 1, Dc = 1.639g / cm3, C66H66Cu4N12O28, Mr = 1729.47, F (000) = 886, μ = 1.294mm-1 and R1 and wR2 were 0.0447 and 0.1141, Two U-shaped binuclear subunits are joined by four carboxyl groups O into a double U-shaped tetranuclear structure with one symmetric center, wherein each U-type subunit comprises two crystallographically asymmetric Cu (II) atoms Each All Cu (Ⅱ) ions are in a distorted quadrangular pyramidal coordination environment, which conforms to the conformation of the cones of Hadip, adip and N, O of phenanthroline Among them, one Cu (Ⅱ) coordinated with water and the other Cu (Ⅱ) coordinated with nitrate. There are extensive hydrogen bonds and π ... π interactions in the crystal structure of the complex.
