DyZn12 crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded in a 20-coordinate geometry to four equivalent Zn(2), eight equivalent Zn(1), and eight equivalent Zn(3) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to two equivalent Dy(1), two equivalent Zn(1), four equivalent Zn(2), and four equivalent Zn(3) atoms to form a mixture of edge, face, and corner-sharing ZnDy2Zn10 cuboctahedra. In the second Zn site, Zn(3) is bonded in a distorted q6 geometry to two equivalent Dy(1), two equivalent Zn(3), four equivalent Zn(1), and four equivalent Zn(2) atoms. In the third Zn site, Zn(2) is bonded in a 10-coordinate geometry to one Dy(1), one Zn(2), four equivalent Zn(1), and four equivalent Zn(3) atoms.
DyZn12 crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded in a 20-coordinate geometry to four equivalent Zn(2), eight equivalent Zn(1), and eight equivalent Zn(3) atoms.
