【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 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.更多还原
