LiAsS2 crystallizes in the monoclinic Cc space group. Li(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form a mixture of edge and corner-sharing LiS6 octahedra. The corner-sharing octahedral tilt angles range from 9-12°. As(1) is bonded in a distorted trigonal non-coplanar geometry to one S(1) and two equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to four equivalent Li(1) and one As(1) atom to form a mixture of edge and corner-sharing SLi4As square pyramids. In the second S site, S(2) is bonded in a see-saw-like geometry to two equivalent Li(1) and two equivalent As(1) atoms.
LiAsS2 crystallizes in the monoclinic Cc space group. Li(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form a mixture of edge and corner-sharing LiS6 octahedra. The corner-sharing octahedral tilt angles range from 9-12°. There is one shorter (2.68 Å) and one longer (2.85 Å) Li(1)-S(2) bond length. There are a spread of Li(1)-S(1) bond distances ranging from 2.68-2.71 Å. As(1) is bonded in a distorted trigonal non-coplanar geometry to one S(1) and two equivalent S(2) atoms. The As(1)-S(1) bond length is 2.18 Å. Both As(1)-S(2) bond lengths are 2.34 Å. There are two inequivalent S sites. In the first S site, S(1) is bonded to four equivalent Li(1) and one As(1) atom to form a mixture of edge and corner-sharing SLi4As square pyramids.
