CuGa2(SO)2 crystallizes in the tetragonal I4/mmm space group. Cu(1) is bonded to two equivalent S(1) and four equivalent O(1) atoms to form CuS2O4 octahedra that share corners with four equivalent Cu(1)S2O4 octahedra and corners with eight equivalent Ga(1)S4 tetrahedra. The corner-sharing octahedra are not tilted. Ga(1) is bonded to four equivalent S(1) atoms to form GaS4 tetrahedra that share corners with four equivalent Cu(1)S2O4 octahedra, corners with four equivalent Ga(1)S4 tetrahedra, and edges with four equivalent Ga(1)S4 tetrahedra. The corner-sharing octahedral tilt angles are 57°. S(1) is bonded in a 5-coordinate geometry to one Cu(1) and four equivalent Ga(1) atoms. O(1) is bonded in a linear geometry to two equivalent Cu(1) atoms.
