In the third Dy site, Dy(3) is bonded in a 4-coordinate geometry to one Ni(1), two equivalent Ni(2), one Ga(1), and one Ga(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 Ga sites. In the first Ga site, Ga(1) is bonded in a body-centered cubic geometry to four equivalent Dy(1) and four equivalent Dy(3) atoms. In the second Ga site, Ga(2) is bonded in a cuboctahedral geometry to four equivalent Dy(1), four equivalent Dy(2), and four equivalent Dy(3) atoms.
