Cr Bi Sb Sb
CrBiSb2 is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrBiSb2 clusters. Cr(1) is bonded in a 2-coordinate geometry to one Bi(1) and one Sb(2) atom. The Cr(1)-Bi(1) bond length is 1.58 Å. The Cr(1)-Sb(2) bond length is 1.46 Å. Bi(1) is bonded in a 1-coordinate geometry to one Cr(1) and one Sb(1) atom. The Bi(1)-Sb(1) bond length is 0.92 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a single-bond geometry to one Bi(1) atom. In the second Sb site, Sb(2) is bonded in a single-bond geometry to one Cr(1) atom.
