摘要： 合成了一种新的四核铁配合物Fe4O2(O2CC2H5)7(bipy)7］PF6·(H2O)2(bipy=2, 2′-联吡啶)。X-射线晶体结构分析表明配合物为单斜晶系，空间群C2/c，晶胞参数a＝28.59(2)Å，b=13.0629(10)Å, c＝17.2698(14)Å, β＝123.6080(10)°， V＝5234.3（7）Å3, Dc=1.559Mg/m3, Z=4。分子结构表明存在两种Fe(Ⅲ)离子的配位环境。一种为2个配位N原子和4个配位O原子，另一种为6个配位O原子；均为畸变八面体。

Abstract: A novel tetranuclear iron(Ⅲ) complex［Fe4O2(O2CC2H5)7(bipy)7］PF6·(H2O)2(bipy=2, 2′-bipyridine) has been synthesized. X-ray crystal structure analysis shows the complex crystallizes in monoclinic system, space group C2/c, unit cell dimensions a=28.59(2)Å, b=13.0629(10)Å, c=17.2698(14)Å, β=123.6080(10)°, V=5234.3(7)Å3, Dc=1.559Mg/m3，Z=4. The molecular structure shows that there are two types of coordination environment for Fe(Ⅲ) atoms. One is formed by two N atoms and four O atoms, another by six O atoms, all in distorted octahedron.

Key words: iron, tetranuclear complex, propionic acid, 2′-bipyridine, crystal structure
