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