Ho6CoBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 4-coordinate geometry to two equivalent Co(1) and two equivalent Bi(1) atoms. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to one Co(1) and four equivalent Bi(1) atoms. Co(1) is bonded in a 9-coordinate geometry to three equivalent Ho(2) and six equivalent Ho(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent Ho(2) atoms.
Ho6CoBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 4-coordinate geometry to two equivalent Co(1) and two equivalent Bi(1) atoms. Both Ho(1)-Co(1) bond lengths are 2.81 Å. Both Ho(1)-Bi(1) bond lengths are 3.30 Å. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to one Co(1) and four equivalent Bi(1) atoms. The Ho(2)-Co(1) bond length is 3.29 Å. All Ho(2)-Bi(1) bond lengths are 3.28 Å. Co(1) is bonded in a 9-coordinate geometry to three equivalent Ho(2) and six equivalent Ho(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent Ho(2) atoms.
