The structure described by 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. is represented by the CIF file [CIF]
