The material described by DyMn12 crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded in a 20-coordinate geometry to four equivalent Mn(3), eight equivalent Mn(1), and eight equivalent Mn(2) atoms. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent Dy(1), two equivalent Mn(1), four equivalent Mn(2), and four equivalent Mn(3) atoms to form a mixture of distorted edge, corner, and face-sharing MnDy2Mn10 cuboctahedra. In the second Mn site, Mn(2) is bonded to two equivalent Dy(1), two equivalent Mn(2), four equivalent Mn(1), and four equivalent Mn(3) atoms to form a mixture of edge, corner, and face-sharing MnDy2Mn10 cuboctahedra. In the third Mn site, Mn(3) is bonded in a 14-coordinate geometry to one Dy(1), four equivalent Mn(1), four equivalent Mn(2), and five equivalent Mn(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
