Syntheses characterization and crystal structure of a novel complex [Cu(Hhbd)(phen)_2]·1.5H_2O·2CH_3OH(Hhbd=Hydroxybutanedioic,phen=1,10-phenanthroline)

利用螯合配体1,10-邻菲咯啉(phen)与羟基丁二酸(H3hbd)及铜盐反应合成了一种新型超分子配合物[Cu(Hhbd)(phen)2].1.5H2O.2CH3OH,通过单晶衍射测定了晶体结构,并用元素分析、红外光谱、热分析等技术对其进行了表征。配合物属三斜晶系,空间群P-1;晶胞参数:a=1.20624(17)nm,b=1.6598(2)nm,c=1.6863(3)nm,α=117.23(9),°β=71.262(3),°γ=117.23(9);°Z=4;最终偏离因子R=0.0420。配合物中每个Cu(Ⅱ)原子与来自两个phen的4个N原子和羟基丁二酸根(Hhbd)的1个O原子配位,形成畸变的三角双锥结构单元。紧邻的单核单元通过phen分子间的π-π堆积作用及Hhbd的羧基O和羟基O与phen环上C原子间的C-H…O氢键的协同作用形成一维zigzag超分子链,毗邻的超分子链籍两种不同氢键相互作用的连接构筑了二维超分子体系。

A novel supramolecular complex, [Cu （Hhbd） （phen）2] · 1.5HaO · 2CHaOH, has been prepared from the reaction of N,N-bidentate ligand （phen）, Hydroxybutanedioic（Hahbd） with a Cu（ Ⅱ ） salt and were characterized by emeans of elemental analysis, thermal analysis, IR and the single crystal X-ray diffraction. The results show that the complex is Triclinic, with space group Pi,a= 1. 20624（17） nm,b= 1. 6598（2） nm,c=l. 6863（3） nm,α= 117.23（9）°,β=71. 262（3）°,γ=117.23（9）°;Z=4 and R=0. 0820. Each Cu（Ⅱ） atom is coordinated by four nitrogen atoms from two phens and one oxygen atom from hydroxybutanedioic with a distorted trigonal bipyramidal geometry. In complex,a 1-D supermolecular zigzag chain is constructed by π-π stacking interactions and C-H…O hydrogen bonds between two mononuclears, furthmore, the neighboring chains are extended into 2-D network structure via differencial hydrogen bonds.
