Ba Ba In As
Ba2InAs is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ba2InAs clusters. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a single-bond geometry to one As(1) atom. The Ba(1)-As(1) bond length is 0.56 Å. In the second Ba site, Ba(2) is bonded in a single-bond geometry to one In(1) atom. The Ba(2)-In(1) bond length is 2.29 Å. In(1) is bonded in a linear geometry to one Ba(2) and one As(1) atom. The In(1)-As(1) bond length is 2.29 Å. As(1) is bonded in a single-bond geometry to one Ba(1) and one In(1) atom.
