[Methylene chain]Inversion-related dimers formed by adjacent molecules in the crystal.
This molecule is a useful precursor to redox active surfactant systems and has the longest unsupported methylene chain to have been examined crystallographically in a ferrocene compound. The undecanone chain is beautifully ordered and bows towards the iron atom. C–H···O and C–H···Br interactions link adjacent molecules in a head-to-tail fashion to stabilize the structure. These dimers assemble further into zigzag chains through C–H···π interactions involving both cyclopentadiene rings.
