摘　　要：以硫酸锌与1,3-二(N-咪唑基甲基)苯(mbix)为原料,用挥发法合成新型二维锌配位聚合物[Zn(mbix)(SO4)].CH3OH(I),其结构经X-射线单晶衍射和元素分析表征。I属正交晶系,空间群Cmc21,晶胞参数a=12.563(5),b=17.122(6),c=8.661(3),V=1862.9(12)3,Z=4,Dc=1.539 g.cm-3,μ=1.464 mm-1,F(000)=888,R1=0.0540,wR2=0.1319。I中Zn2+与两个mbix配体的两个氮原子和两个SO42-配体的两个氧原子配位,形成一个畸变的四面体几何构型。Zn2+经SO24-离子桥联形成一维波浪状链,链与链之间又通过mbix配体形成二维格子层状结构。A novel two dimensional Zn（II） complex,{[Zn（mbix）（SO4）]·CH3OH}n（I）,was synthesize by volatile reactions of zinc sulfate and 1,3-bis（imidazol-1-ylmethyl）benzene（mbix）.The structure was characterized by X-ray single crystal diffraction and elemental analysis.The crystal of I belongs to Orthorhombic,space group Cmc21 with a = 12.563（5）,b =17.122（6）,c=8.661（3）,V=1862.9（12）3,Z=4,Dc=1.539 g·cm-3,μ=1.464 mm-1,F（000） =888,R1=0.0540,wR2=0.1319.The Zn atom is four-coordinated with slightly distorted tetrahedral coordination geometry by two N atoms from two mbix ligands and two O atoms from two SO2-4 ions.The Zn2＋ ions is bridged by the SO2-4 ions into a wavy chain,which is further linked into grid network by mbix ligands.
