Lu6MnBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to two equivalent Mn(1) and two equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing LuMn2Bi2 tetrahedra. In the second Lu site, Lu(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 Lu(2) and six equivalent Lu(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Lu(1) and six equivalent Lu(2) atoms.

In the first Lu site, Lu(1) is bonded to two equivalent Mn(1) and two equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing LuMn2Bi2 tetrahedra. Both Lu(1)-Mn(1) bond lengths are 2.85 Å. Both Lu(1)-Bi(1) bond lengths are 3.16 Å. In the second Lu site, Lu(2) is bonded in a 5-coordinate geometry to one Mn(1) and four equivalent Bi(1) atoms. The Lu(2)-Mn(1) bond length is 3.13 Å. All Lu(2)-Bi(1) bond lengths are 3.28 Å. Mn(1) is bonded in a 9-coordinate geometry to three equivalent Lu(2) and six equivalent Lu(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Lu(1) and six equivalent Lu(2) atoms.
