BaCu2S2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a body-centered cubic geometry to eight equivalent S(1) atoms. Cu(1) is bonded to four equivalent S(1) atoms to form a mixture of corner and edge-sharing CuS4 tetrahedra. S(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Cu(1) atoms.
