Nd5Ir2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 2-coordinate geometry to three equivalent Ir(1) atoms. In the second Nd site, Nd(3) is bonded to four equivalent Ir(1) atoms to form distorted edge-sharing NdIr4 tetrahedra. In the third Nd site, Nd(2) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. Ir(1) is bonded in a 8-coordinate geometry to two equivalent Nd(3), three equivalent Nd(1), and three equivalent Nd(2) atoms.
Nd5Ir2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 2-coordinate geometry to three equivalent Ir(1) atoms. There are a spread of Nd(1)-Ir(1) bond distances ranging from 2.82-3.59 Å. In the second Nd site, Nd(3) is bonded to four equivalent Ir(1) atoms to form distorted edge-sharing NdIr4 tetrahedra. There are two shorter (2.99 Å) and two longer (3.02 Å) Nd(3)-Ir(1) bond lengths. In the third Nd site, Nd(2) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. There are a spread of Nd(2)-Ir(1) bond distances ranging from 2.88-3.22 Å. Ir(1) is bonded in a 8-coordinate geometry to two equivalent Nd(3), three equivalent Nd(1), and three equivalent Nd(2) atoms.
