The crystal structure described by AlBr3 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two al2br6 molecules. Al(1) is bonded to one Br(1), one Br(2), and two equivalent Br(3) atoms to form edge-sharing AlBr4 tetrahedra. There are three inequivalent Br sites. In the first Br site, Br(2) is bonded in a single-bond geometry to one Al(1) atom. In the second Br site, Br(1) is bonded in a single-bond geometry to one Al(1) atom. In the third Br site, Br(3) is bonded in an L-shaped geometry to two equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
