Ho6MnBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to two equivalent Mn(1) and two equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing HoMn2Bi2 tetrahedra. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to one Mn(1) and four equivalent Bi(1) atoms. Mn(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.

In the first Ho site, Ho(1) is bonded to two equivalent Mn(1) and two equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing HoMn2Bi2 tetrahedra. Both Ho(1)-Mn(1) bond lengths are 2.92 Å. Both Ho(1)-Bi(1) bond lengths are 3.21 Å. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to one Mn(1) and four equivalent Bi(1) atoms. The Ho(2)-Mn(1) bond length is 3.26 Å. All Ho(2)-Bi(1) bond lengths are 3.33 Å. Mn(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.
