摘　　要：合成了新型配合物{(n-Bu)_(2)Sn[(η^(5)-C_(5)H_(5))Fe(η^(5)-C_(5)H_(4))COO]_(2)}_(2),用元素分析、红外光谱和核磁共振谱(^(1)H、^(13)C、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P2_(1)/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)A^(3),Z=4,Dc=1.614Mg@m^(-3),μ(MoKα)=1.912mm^(-1),F(000)=2800,最终可靠因子R_(1)=0.0827,wR_(2)=0.2085.配合物分子呈中心对称,是具有Sn_(2)O_(2)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)_(2)Sn[(η^(5)-C_(5)H_(5))Fe(η^(5)-C_(5)H_(4))COO]_(2)}_(2)has been synthesized and characterized by elemental analysis,IR and NMR(^(1)H,^(13)C 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 R_(1)=0.0827,wR_(2)=0.2085.The title complex molecule structure has binuclear centrosymmetric dimeric structure in which features a planar Sn_(2)O_(2) 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.
