摘　　要： 合成了新型配合物{(n-Bu)2Sn[(η5-C5H5)Fe(η5-C5H4)COO]2}2,用元素分析、红外光谱和核磁共振谱(1H、13C、119Sn)进行了表征,并用X-射线单晶衍射分析法测定其晶体结构.晶体属单斜晶系,空间群P21/c,晶胞参数a=11.753(4)A,b=21.133(7)A,c=23.374(9)A,β=101.62(3)°,V=5687(4)A3,Z=4,Dc=1.614Mg@m-3,μ(MoKα)=1.912mm-1,F(000)=2800,最终可靠因子R1=0.0827,wR2=0.2085.配合物分子呈中心对称,是具有Sn2O2中心内环的二聚体结构;每个锡原子与5个O原子和2个C原子形成扭曲的五角双锥几何构型,其中5个O原子为赤道配位原子,而C-Sn-C为配合物的轴. The novel complex {(n-Bu)_2Sn[(η~5-C_5H_5)Fe(η~5-C_5H_4)COO]_2}_2 has been synthesized and characterized by elemental analysis, IR and NMR(1H, 13C and 119Sn) spectroscopy. The crystal structure of the title complex has been determined by single crystal X ray diffraction techniques. The crystal belongs to monoclinic with space group P21/c. The cell parameters are: a=11.753(4)?, b=21.133(7)?, c=23.374(9)?, β=101.62(3)°, V=5687(4)?3, Z=4, Dc=1.614Mg·m-3, μ(MoKα)=1.912mm-1, F(000)=2800. The structure was refined to final R1=0.0827, wR2=0.2085. The title complex molecule structure has binuclear centrosymmetric dimeric structure in which features a planar Sn2O2 core. In the structure thetin atoms rendered seven coordination in a distorted pentagonal bipyramidal structure. The oxygen atoms O1, O2, O3, O4, O3A formed the equatorial plane and C23 Sn1 C27 is the axis of the title complex. CCDC: 193108.
