CuAlTe2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Cu(1) is bonded to four equivalent Te(1) atoms to form CuTe4 tetrahedra that share corners with four equivalent Cu(1)Te4 tetrahedra and corners with eight equivalent Al(1)Te4 tetrahedra. Al(1) is bonded to four equivalent Te(1) atoms to form AlTe4 tetrahedra that share corners with four equivalent Al(1)Te4 tetrahedra and corners with eight equivalent Cu(1)Te4 tetrahedra. Te(1) is bonded to two equivalent Cu(1) and two equivalent Al(1) atoms to form corner-sharing TeAl2Cu2 tetrahedra.
