LiIn2As crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one LiIn2As cluster. Li(1) is bonded in a distorted water-like geometry to one In(1) and one As(1) atom. The Li(1)-In(1) bond length is 0.68 Å. The Li(1)-As(1) bond length is 1.23 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a single-bond geometry to one Li(1) atom. In the second In site, In(2) is bonded in a single-bond geometry to one As(1) atom. The In(2)-As(1) bond length is 0.75 Å. As(1) is bonded in a distorted water-like geometry to one Li(1) and one In(2) atom.
