Nd5Pb3 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 Pb(1) atoms. In the second Nd site, Nd(2) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1) and five equivalent Nd(2) atoms.
Nd5Pb3 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 Pb(1) atoms. All Nd(1)-Pb(1) bond lengths are 3.36 Å. In the second Nd site, Nd(2) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. There are a spread of Nd(2)-Pb(1) bond distances ranging from 3.22-3.75 Å. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1) and five equivalent Nd(2) atoms.
