CuAlBr4 crystallizes in the tetragonal P-42c space group. Cu(1) is bonded to four equivalent Br(1) atoms to form CuBr4 tetrahedra that share corners with four equivalent Al(1)Br4 tetrahedra. Al(1) is bonded to four equivalent Br(1) atoms to form AlBr4 tetrahedra that share corners with four equivalent Cu(1)Br4 tetrahedra. Br(1) is bonded in a water-like geometry to one Cu(1) and one Al(1) atom.
