In Bi Sb Sb
InBiSb2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two InBiSb2 clusters. In(1) is bonded in a single-bond geometry to one Bi(1), one Sb(1), and one Sb(2) atom. The In(1)-Bi(1) bond length is 0.50 Å. The In(1)-Sb(1) bond length is 2.01 Å. The In(1)-Sb(2) bond length is 0.28 Å. Bi(1) is bonded in a 2-coordinate geometry to one In(1) and one Sb(2) atom. The Bi(1)-Sb(2) bond length is 0.37 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a single-bond geometry to one In(1) atom. In the second Sb site, Sb(2) is bonded in a distorted single-bond geometry to one In(1) and one Bi(1) atom.
