Synthesis, spectroscopic characterization and crystal structure of complex {(n-Bu)2Sn[(η5-C5H5)Fe(η5-C5H4)COO]2}2

The novel complex {(n-Bu)(2)Sn[(eta(5)-C5H5) Fe(eta(5)-C5H4)COO](2)}(2) has been synthesized and characterized by elemental analysis, IR and NMR(H-1, C-13 and Sn-119) 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 P2(1)/c. The cell parameters are: a = 11. 753(4)Angstrom, b = 21. 133(7)Angstrom, c = 23. 374(9)Angstrom, beta = 101. 62(3)degrees, V = 5687(4)Angstrom(3), Z = 4, D-c = 1. 614Mg (.) m(-3), mu(MoKalpha) = 1. 912mm(-1), F(OOO) = 2800. The structure was refined to final R-1 = 0.0827, w R-2 = 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 pent agonal 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.
