Al Co Co Bi
Co2AlBi crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Co2AlBi cluster. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a single-bond geometry to one Al(1) atom. The Co(1)-Al(1) bond length is 0.89 Å. In the second Co site, Co(2) is bonded in a bent 150 degrees geometry to one Al(1) and one Bi(1) atom. The Co(2)-Al(1) bond length is 1.97 Å. The Co(2)-Bi(1) bond length is 1.11 Å. Al(1) is bonded in a 1-coordinate geometry to one Co(1) and one Co(2) atom. Bi(1) is bonded in a 1-coordinate geometry to one Co(2) atom.
