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