The ferrocenium cation of the title compound, [Fe(C5H5)2][Sn2Br5(CH3)4], has parallel cyclopentadienyl rings with eclipsed conformations. The Sn atom of the anion is in a distorted square-pyramidal coordination. Alternatively, it can be described as having a distorted octahedral coordination to form infinite chains of two edge-shared octahedra parallel to the b axis.
