Cu2CdSnTe4 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 Cu(1)Te4 tetrahedra, corners with four equivalent Cd(1)Te4 tetrahedra, and corners with four equivalent Sn(1)Te4 tetrahedra. Cd(1) is bonded to four equivalent Te(1) atoms to form CdTe4 tetrahedra that share corners with four equivalent Sn(1)Te4 tetrahedra and corners with eight equivalent Cu(1)Te4 tetrahedra. Sn(1) is bonded to four equivalent Te(1) atoms to form SnTe4 tetrahedra that share corners with four equivalent Cd(1)Te4 tetrahedra and corners with eight equivalent Cu(1)Te4 tetrahedra. Te(1) is bonded to two equivalent Cu(1), one Cd(1), and one Sn(1) atom to form corner-sharing TeCdCu2Sn tetrahedra.
