| Abstract: The novel complex {(n-Bu)2Sn[(η5-C5H5)Fe(η5-C5H4)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 the tin 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. |
