The compound described by TlTlAl2Br8 is Indium-derived structured and crystallizes in the monoclinic P2/c space group. The structure is zero-dimensional and consists of two 7440-28-0 atoms and two TlAl2Br8 clusters. In each TlAl2Br8 cluster, Tl(1) is bonded in a 2-coordinate geometry to two equivalent Br(4) atoms. Al(1) is bonded in a tetrahedral geometry to one Br(1), one Br(2), one Br(3), and one Br(4) atom. There are four inequivalent Br sites. In the first Br site, Br(1) is bonded in a single-bond geometry to one Al(1) atom. In the second Br site, Br(2) is bonded in a single-bond geometry to one Al(1) atom. In the third Br site, Br(3) is bonded in a single-bond geometry to one Al(1) atom. In the fourth Br site, Br(4) is bonded in a distorted single-bond geometry to one Tl(1) and one Al(1) atom. is represented by the CIF file [CIF]
