In Bi Br Br
InBiBr2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two InBiBr2 clusters. In(1) is bonded in a single-bond geometry to one Bi(1) and one Br(2) atom. The In(1)-Bi(1) bond length is 2.70 Å. The In(1)-Br(2) bond length is 0.45 Å. Bi(1) is bonded in a linear geometry to one In(1) and one Br(1) atom. The Bi(1)-Br(1) bond length is 3.15 Å. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a single-bond geometry to one Bi(1) atom. In the second Br site, Br(2) is bonded in a single-bond geometry to one In(1) atom.
