Dy6MnBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to two equivalent Mn(1) and two equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing DyMn2Bi2 tetrahedra. In the second Dy site, Dy(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 Dy(2) and six equivalent Dy(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1) and six equivalent Dy(2) atoms.

In the first Dy site, Dy(1) is bonded to two equivalent Mn(1) and two equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing DyMn2Bi2 tetrahedra. Both Dy(1)-Mn(1) bond lengths are 2.94 Å. Both Dy(1)-Bi(1) bond lengths are 3.22 Å. In the second Dy site, Dy(2) is bonded in a 5-coordinate geometry to one Mn(1) and four equivalent Bi(1) atoms. The Dy(2)-Mn(1) bond length is 3.29 Å. All Dy(2)-Bi(1) bond lengths are 3.34 Å. Mn(1) is bonded in a 9-coordinate geometry to three equivalent Dy(2) and six equivalent Dy(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1) and six equivalent Dy(2) atoms.
