CuCd2GaTe4 is Stannite structured and crystallizes in the tetragonal I-42m space group. Cu(1) is bonded to four equivalent Te(1) atoms to form CuTe4 tetrahedra that share corners with four equivalent Ga(1)Te4 tetrahedra and corners with eight equivalent Cd(1)Te4 tetrahedra. Cd(1) is bonded to four equivalent Te(1) atoms to form CdTe4 tetrahedra that share corners with four equivalent Cu(1)Te4 tetrahedra, corners with four equivalent Cd(1)Te4 tetrahedra, and corners with four equivalent Ga(1)Te4 tetrahedra. Ga(1) is bonded to four equivalent Te(1) atoms to form GaTe4 tetrahedra that share corners with four equivalent Cu(1)Te4 tetrahedra and corners with eight equivalent Cd(1)Te4 tetrahedra. Te(1) is bonded to one Cu(1), two equivalent Cd(1), and one Ga(1) atom to form corner-sharing TeCd2GaCu tetrahedra.
