LiCuS crystallizes in the tetragonal I4/mmm space group. Li(1) is bonded in a distorted see-saw-like geometry to four equivalent S(1) atoms. Cu(1) is bonded in a linear geometry to two equivalent S(1) atoms. S(1) is bonded to four equivalent Li(1) and two equivalent Cu(1) atoms to form a mixture of corner and edge-sharing SLi4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 3-22°.
LiCuS crystallizes in the tetragonal I4/mmm space group. Li(1) is bonded in a distorted see-saw-like geometry to four equivalent S(1) atoms. There are two shorter (2.43 Å) and two longer (2.59 Å) Li(1)-S(1) bond lengths. Cu(1) is bonded in a linear geometry to two equivalent S(1) atoms. Both Cu(1)-S(1) bond lengths are 2.14 Å. S(1) is bonded to four equivalent Li(1) and two equivalent Cu(1) atoms to form a mixture of corner and edge-sharing SLi4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 3-22°.
