In the second Dy site, Dy(2) is bonded in a 4-coordinate geometry to one Ni(2), two equivalent Ni(1), and one Sn(2) atom. In the third Dy site, Dy(3) is bonded in a 5-coordinate geometry to one Ni(1), two equivalent Ni(2), one Sn(1), and one Sn(2) atom. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 8-coordinate geometry to two equivalent Dy(1), two equivalent Dy(3), and four equivalent Dy(2) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent Dy(1), two equivalent Dy(2), four equivalent Dy(3), and one Ni(2) atom. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a body-centered cubic geometry to four equivalent Dy(1) and four equivalent Dy(3) atoms. In the second Sn site, Sn(2) is bonded in a cuboctahedral geometry to four equivalent Dy(1), four equivalent Dy(2), and four equivalent Dy(3) atoms.
