Li2CuS2 is Hazelwoodite-derived structured and crystallizes in the tetragonal P4_2/nmc space group. Li(1) is bonded to four equivalent S(1) atoms to form a mixture of distorted corner and edge-sharing LiS4 tetrahedra. Cu(1) is bonded in a 4-coordinate geometry to four equivalent S(1) atoms. S(1) is bonded in a 6-coordinate geometry to four equivalent Li(1) and two equivalent Cu(1) atoms.
Li2CuS2 is Hazelwoodite-derived structured and crystallizes in the tetragonal P4_2/nmc space group. Li(1) is bonded to four equivalent S(1) atoms to form a mixture of distorted corner and edge-sharing LiS4 tetrahedra. There are two shorter (2.46 Å) and two longer (2.47 Å) Li(1)-S(1) bond lengths. Cu(1) is bonded in a 4-coordinate geometry to four equivalent S(1) atoms. There are two shorter (2.30 Å) and two longer (2.31 Å) Cu(1)-S(1) bond lengths. S(1) is bonded in a 6-coordinate geometry to four equivalent Li(1) and two equivalent Cu(1) atoms.
