InAlSb2 is Chalcopyrite-like structured and crystallizes in the tetragonal P-4m2 space group. In(1) is bonded to four equivalent Sb(1) atoms to form InSb4 tetrahedra that share corners with four equivalent In(1)Sb4 tetrahedra and corners with eight equivalent Al(1)Sb4 tetrahedra. Al(1) is bonded to four equivalent Sb(1) atoms to form AlSb4 tetrahedra that share corners with four equivalent Al(1)Sb4 tetrahedra and corners with eight equivalent In(1)Sb4 tetrahedra. Sb(1) is bonded to two equivalent In(1) and two equivalent Al(1) atoms to form corner-sharing SbAl2In2 tetrahedra.
