Tris(4,4'-bi-1,3-thia-zole-κN,N')iron(II) tetra-bromidoferrate(III) bromide.

In the [Fe(4,4'-bit)(3)](2+) (4,4'-bit is 4,4'-bi-1,3-thia-zole) cation of the title compound, [Fe(C(6)H(4)N(2)S(2))(3)][FeBr(4)]Br, the Fe(II) atom (3 symmetry) is six-coordinated in a distorted octa-hedral geometry by six N atoms from three 4,4'-bit ligands. In the [FeBr(4)](-) anion, the Fe(III) atom (3 symmetry) is four-coordinated in a distorted tetra-hedral geometry. In the crystal, inter-molecular C-H⋯Br hydrogen bonds and Br⋯π inter-actions [Br⋯centroid distances = 3.562 (3) and 3.765 (2) Å] link the cations and anions, stabilizing the structure.
