Nd5Ir3 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 5-coordinate geometry to two equivalent Ir(2) and three equivalent Ir(1) atoms. In the second Nd site, Nd(2) is bonded to four equivalent Ir(1) atoms to form edge-sharing NdIr4 tetrahedra. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to two equivalent Nd(2) and six equivalent Nd(1) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to eight equivalent Nd(1) atoms.
Nd5Ir3 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 5-coordinate geometry to two equivalent Ir(2) and three equivalent Ir(1) atoms. There is one shorter (2.98 Å) and one longer (3.07 Å) Nd(1)-Ir(2) bond length. There are a spread of Nd(1)-Ir(1) bond distances ranging from 2.93-3.28 Å. In the second Nd site, Nd(2) is bonded to four equivalent Ir(1) atoms to form edge-sharing NdIr4 tetrahedra. All Nd(2)-Ir(1) bond lengths are 2.94 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to two equivalent Nd(2) and six equivalent Nd(1) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to eight equivalent Nd(1) atoms.
