用Zn(NO3)2,phen(邻菲咯啉)和phth(邻苯二甲酸)混合反应得到了配位聚合物{[Zn2(phen)2(phth)2(H2O)2]·2H2O}n.通过元素分析、红外光谱对配合物进行了表征.用X射线单晶衍射仪测定了配合物的晶体结构.配合物为单斜晶系,P2(1)/n空间群.晶胞参数a=0.9643(3)nm,b=0.8976(3)nm,c=2.1410(7)nm,β=90.776(5)°,Z=4,V=1.8531(10)nm3,Dc=1.598g/cm3,μ=1.367mm-1,F(000)=912,R1=0.0409,wR2=0.0818,锌原子为五配位,呈畸变三角双锥构型,通过邻苯二甲酸根的桥联作用形成了一维螺旋链状结构,相邻的螺旋链之间靠π-π堆积形成二维网状超分子结构.

Novel supramolecular complex {[Zn2(phen)2(phth)2(H2O)2]·2H2O}n (phen=phenanthroline; phth=phthalate) has been synthesized by the reaction of phen and phth with zinc(Ⅱ) salt.Elemental analysis, IR spectra and X-ray crystal structure analysis were carried out to determine the composition and crystal structure of title complex.The title complex belongs to monoclinic system with space group P2(1)/n, a=0.9643(3) nm, b=0.8976(3) nm, c=2.1410(7) nm, β=90.776(5)°, Z=4, V=1.8531(10) nm3, Dc=1.598 g/cm3, μ=1.367 mm-1, F(000)=912, R1=0.0409, wR2=0.0818, and the zinc atom rendered five-coordinate in a distorted trigonal bipyramidal configuration.The complex formed 1-D helix chain bridged by phth and 2-D network structure by π-π action of neighbouring helix chain.
