CuZn2GaSe4 is Stannite structured and crystallizes in the tetragonal I-42m space group. Cu(1) is bonded to four equivalent Se(1) atoms to form CuSe4 tetrahedra that share corners with four equivalent Ga(1)Se4 tetrahedra and corners with eight equivalent Zn(1)Se4 tetrahedra. Zn(1) is bonded to four equivalent Se(1) atoms to form ZnSe4 tetrahedra that share corners with four equivalent Cu(1)Se4 tetrahedra, corners with four equivalent Zn(1)Se4 tetrahedra, and corners with four equivalent Ga(1)Se4 tetrahedra. Ga(1) is bonded to four equivalent Se(1) atoms to form GaSe4 tetrahedra that share corners with four equivalent Cu(1)Se4 tetrahedra and corners with eight equivalent Zn(1)Se4 tetrahedra. Se(1) is bonded to one Cu(1), two equivalent Zn(1), and one Ga(1) atom to form corner-sharing SeZn2GaCu tetrahedra.
