CrIn2Al is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrIn2Al clusters. Cr(1) is bonded in a linear geometry to one In(1) and one In(2) atom. The Cr(1)-In(1) bond length is 1.47 Å. The Cr(1)-In(2) bond length is 1.47 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a single-bond geometry to one Cr(1) atom. In the second In site, In(2) is bonded in a distorted single-bond geometry to one Cr(1) and one Al(1) atom. The In(2)-Al(1) bond length is 2.56 Å. Al(1) is bonded in a single-bond geometry to one In(2) atom.
