| Abstract: The title complex crystallizes in monoclinic system with space group P21/n, a = 15.244(4)Å, b = 20.895(7)Å, c = 12.375(4)Å, B = 97.39(3)Å, Z = 4, Mr = 933.84, V= 3909(2)Å3, Dc = 1.5879.cm-3, F(000) = 1872.The final R = 0.0684.It has tetranuclear centrosymmetric dimeric structure.The molecule features a planar Sn2O2 unit with two exo-cyclic tin atoms connected to two bridging oxygen atoms of the Sn2O2 unit.There are two independent FcCOO (Fc = ferrocenyl) ligands in the structure, one is bidentate bridging and bridges both the endo- and exo-cyclic tin atoms by using both oxygen atoms, and other is monodentate and coordinated only to exo-cyclic tin atom.The result is that both tin atoms are five-coordination, have a distorted trigonal bipyramidal geometry with an additional week interaction between another oxygen atom and tin atom.Its crystal structure differs from the similar {[FcCO2Sn(n-Bu)2]O}2·4C6H6 at all.However there are inevitable relationship between them.The variety of the structural mode of this kind of organotin compounds predicts the internal factor about its chemical reactivity and bio-activity, and will provide experimental grounds for new kinetic process mode of coordinate chemistry. |
