中文摘要：

以Fe（ClO4）2.6H2O和N,N＇,N＇＇,N＇＇＇-四（2-吡啶甲基）-1,4,8,11-四氮杂环十四烷（tpmc）为原料,采用溶液界面扩散法,在二氯甲烷与乙醇两相溶剂的界面上制得Fe（Ⅱ）的双核配合物[Fe2（μ2-OH）（C34H44N8）]（ClO4）3.EtOH（1）,其结构经X-射线单晶衍射表征。1属正交晶系,Pbcm空间群,晶胞参数a=11.652（2）,b=17.505（4）,c=22.256（5）,α=β=γ=90°,V=453 9.7（16）3,Z=4,Dc=1.519 g.cm-3,μ=0.887 mm-1,F（000）=2 152,R1=0.058 3,ωR2=0.175 8。1中的Fe（Ⅱ）分别与外向型配体tpmc的十四元环上的两个氮原子,两个吡啶环上的氮原子和μ2-OH上的氧原子配位,形成一个畸变的三角双锥几何构型。连接两个Fe（Ⅱ）核中心的μ2-OH氧桥以及分子内和分子间的氢键缔合作用,增强了晶体结构的稳定性。

英文摘要：

Hydroxo-bridged binuclear complex,[Fe2（μ2-OH）（tpmc）]（ClO4）3·EtOH（1）,was synthesized through by reaction of N,N＇,N＇＇,N＇＇＇-tetrakis（2-pyridylmethyl）-1,4,8,11-tetraazacyclotetradecane（tpmc） with ferrous perchiorate hexahydrated by the liquid diffusion method,at the interface of dichloromethane and ethanol solvent.The structure was characterized by X-ray single crystal diffraction.1 belongs to orthorhombic system,space group Pbcm with a=11.652（2）,b=17.505（4） ,c=22.256（5）,α=β=γ=90°,V=4 539.7（16）3,Z=4,Dc=1.519 g·cm-3,μ=0.887 mm-1,F（000）=2 152,R1=0.058 3,ωR2=0.175 8.Each iron（Ⅱ） ion is coordinated with four nitrogen atoms in an exo arrangement of tpmc groups while the additional μ2-hydroxo bridges metal-ion centers.The coordination geometry about the Fe（Ⅱ） atoms may be regarded as a distorted trigonal bipyramid.The crystal structure is stabilized by the μ2-OH which bridges two Fe（Ⅱ） centers and intra-and inter-molecular hydrogen bond association function.
