Partial packing diagram of compound 8, showing the Br⋯π and π–π contacts (Å). Colour codes as defined by Mercury: carbon dark grey, hydrogen light grey, iron orange, mercury blue and bromine brown; the red lines are unexpanded contacts and the cyan lines are expanded contacts. Ct1′/Ct1′′ and Ct2′/Ct2′′ are the centroids of inversion-related cyclopentadienyl rings, with one Fe atom between Ct1′ and Ct2′, and another between Ct1′′ and Ct2′′. |
