Abstract: Complexes E(η5-Me3SiC5H3)2 [Fe(CO)]2(μ-CO)2[E=Me2Si(1),Me2SiOSiMe2(2)] were obtained by reaction of bridged compounds E(Me3SiC5H4)2[E=Me2Si(Ⅰ),Me2SiOSiMe2(Ⅱ)]with Fe(CO)5 in refluxing xylene.Compounds 1,2 were revealed to be cis-isomers by 1H NMRspectra and X-ray diffraction analysis.Extensive desilylation was observed.Crystals of 1 and 2 are monoclinic, belonging to space-group P21/m.1:a=0.7359(3)nm,b=1.9409(1)nm,c=0.9383(5)nm,β=99.71(4)°,V=1.32010(1) nm3,Z= 2,Dc=1.394 g/mL;2:α=0.6743(5)nm,b=2.2635(5)nm,c=1.0802(1) nm,β= 108.1(2)°,V=1.5668(2)nm3 Z=2,Dc=1.493 g/mL.
