The material structure described by GaAlSb2 is Lavarevi\'{c}ite-like structured and crystallizes in the trigonal R3m space group. Ga(1) is bonded to one Sb(2) and three equivalent Sb(1) atoms to form GaSb4 tetrahedra that share corners with six equivalent Ga(1)Sb4 tetrahedra and corners with six equivalent Al(1)Sb4 tetrahedra. Al(1) is bonded to one Sb(1) and three equivalent Sb(2) atoms to form AlSb4 tetrahedra that share corners with six equivalent Ga(1)Sb4 tetrahedra and corners with six equivalent Al(1)Sb4 tetrahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to three equivalent Ga(1) and one Al(1) atom to form SbAlGa3 tetrahedra that share corners with six equivalent Sb(2)Al3Ga tetrahedra and corners with six equivalent Sb(1)AlGa3 tetrahedra. In the second Sb site, Sb(2) is bonded to one Ga(1) and three equivalent Al(1) atoms to form SbAl3Ga tetrahedra that share corners with six equivalent Sb(2)Al3Ga tetrahedra and corners with six equivalent Sb(1)AlGa3 tetrahedra. is represented by the CIF card [CIF]
