LiAsCl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LiAsCl clusters. Li(1) is bonded in a single-bond geometry to one Cl(1) atom. The Li(1)-Cl(1) bond length is 1.57 Å. As(1) is bonded in a single-bond geometry to one Cl(1) atom. The As(1)-Cl(1) bond length is 2.03 Å. Cl(1) is bonded in a linear geometry to one Li(1) and one As(1) atom.
