LiAgAs2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LiAgAs2 clusters. Li(1) is bonded in a 3-coordinate geometry to one Ag(1) and two equivalent As(1) atoms. The Li(1)-Ag(1) bond length is 0.19 Å. Both Li(1)-As(1) bond lengths are 0.48 Å. Ag(1) is bonded in a single-bond geometry to one Li(1) atom. As(1) is bonded in a single-bond geometry to one Li(1) atom.
