A new bridged ligand incorporating the hexamethylindenyl moiety has been synthesized and usedto prepare the corresponding ansa ferrocene, [Fe(
5-C9Me6)(5-C5H4)SiMe2], 10, which is the first mixed-ring[1]ferrocenophane to be structurally characterized. Comparison of the crystal structure of 10 with those of [Fe(5-C5H4)2SiMe2], 1, and rac-[Fe(5-C9Me6)2SiMe2], 5a,shows many structural features, such as the ring tilt of17
, to be intermediate between those of the two modelcompounds, while the average Si-C(ipso) bond lengthis much closer to that in 5a.
