Cr Co Bi Bi
CrCoBi2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrCoBi2 clusters. Cr(1) is bonded in a 2-coordinate geometry to one Co(1) and one Bi(2) atom. The Cr(1)-Co(1) bond length is 1.81 Å. The Cr(1)-Bi(2) bond length is 1.63 Å. Co(1) is bonded in a distorted single-bond geometry to one Cr(1) and one Bi(1) atom. The Co(1)-Bi(1) bond length is 0.84 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a single-bond geometry to one Co(1) atom. In the second Bi site, Bi(2) is bonded in a single-bond geometry to one Cr(1) atom.
