Nd5Sn3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 6-coordinate geometry to six equivalent Sn(1) atoms. In the second Nd site, Nd(2) is bonded in a 5-coordinate geometry to five equivalent Sn(1) atoms. Sn(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1) and five equivalent Nd(2) atoms.
Nd5Sn3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 6-coordinate geometry to six equivalent Sn(1) atoms. All Nd(1)-Sn(1) bond lengths are 3.33 Å. In the second Nd site, Nd(2) is bonded in a 5-coordinate geometry to five equivalent Sn(1) atoms. There are a spread of Nd(2)-Sn(1) bond distances ranging from 3.20-3.72 Å. Sn(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1) and five equivalent Nd(2) atoms.
