Cu3CdGaSe4 crystallizes in the cubic P-43m space group. The structure is three-dimensional. Cu1+ is bonded to four equivalent Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent CdSe4 tetrahedra, corners with eight equivalent CuSe4 tetrahedra, and edges with two equivalent GaSe4 tetrahedra. All Cu–Se bond lengths are 2.52 Å. Cd2+ is bonded to four equivalent Se2- atoms to form CdSe4 tetrahedra that share corners with four equivalent GaSe4 tetrahedra and corners with twelve equivalent CuSe4 tetrahedra. All Cd–Se bond lengths are 2.66 Å. Ga3+ is bonded to four equivalent Se2- atoms to form GaSe4 tetrahedra that share corners with four equivalent CdSe4 tetrahedra and edges with six equivalent CuSe4 tetrahedra. All Ga–Se bond lengths are 2.45 Å. Se2- is bonded in a distorted pentagonal planar geometry to three equivalent Cu1+, one Cd2+, and one Ga3+ atom.
