Abstract

Abstract: The cyclic compounds of Me₂Si[η⁵-C₅H₄Fe(CO)₂]₂SnR₂[R=Cl(1),Me(2),Ph(3)] were synthesized via insertion of SnCl₂ to Fe-Fe bond of complex 1,Me₂Si[η⁵-C₅H₄Fe(CO)]₂(μ-CO)₂ and the reactions of the related dianion {Me₂Si[η⁵-C₅H₄Fe(CO)₂]₂}^2-with R₂SnCl₂(R=Me,PH).They were characterized by IR,¹H NMR and elementary analysis. No expected product was isolated from the corresponding reactions of complex 2,(η⁵,η⁵C₅H₄SiMe₂OSiMe₂H₄)[Fe (CO)]₂(μ-CO)₂.The crystal structure of 3 was determined by X-ray diffraction. The crystals of 3 are monoclinic,space group P2₁/n with a=1. 0384(3)nm,b=1.6384(1) nm,c=1.5762(5) nm and β=97.93(2)°,V=2.656(2) nm³,Z=4,D_x=1.71g/mL.The final agreement factor,R=0.036.

Key words: Bridged biscyclopentadienyl, Hetero-nuclear metallic complex, Cyclic compound
