Materials Data on NdIr5 by Materials Project

NdIr5 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Nd is bonded in a 6-coordinate geometry to eighteen Ir atoms. There are six shorter (3.09 Å) and twelve longer (3.44 Å) Nd–Ir bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded to four equivalent Nd and eight Ir atoms to form a mixture of edge, face, and corner-sharing IrNd4Ir8 cuboctahedra. There are four shorter (2.66 Å) and four longer (2.68 Å) Ir–Ir bond lengths. In the second Ir site, Ir is bonded in a 12-coordinate geometry to three equivalent Nd and six equivalent Ir atoms.
