摘要
合成了一种新的四核铁配合物 [Fe4 O2 (O2 CC2 H5) 7(bipy) 2 ]PF6 ·(H2 O) 2 (bipy =2 ,2′ 二联吡啶 )。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 =2 8 59(2 ) ,b =13 0 6 2 9(10 ) ,c =17 2 6 98(14) ,β =12 3 6 0 80 (10 )° ,V =52 34 3(7) 3,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 ;
A novel tetranuclear iron(Ⅲ) complex[Fe 4O 2(O 2CC 2H 5) 7(bipy) 2]PF 6·(H 2O) 2(bipy= 2,2′ bipyridine) has been synthesized. X\|ray crystal structure analysis shows the complex crystallizes in monoclinic system,space group C \-2/ c ,unit cell dimensions a =28.59(2)?, b =13.0629(10)?, c =17.2698(14)?, β =123.6080(10)°, V =5234.3(7)? 3, D c=1.559?Mg/m 3, 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.
