Materials Data on Nd4MgPt by Materials Project
MgNd4Pt crystallizes in the cubic F-43m space group. The structure is three-dimensional. Mg is bonded to three equivalent Mg and nine Nd atoms to form a mixture of corner and face-sharing MgNd9Mg3 cuboctahedra. All Mg–Mg bond lengths are 3.21 Å. There are a spread of Mg–Nd bond distances ranging from 3.45–3.66 Å. There are three inequivalent Nd sites. In the first Nd site, Nd is bonded in a 3-coordinate geometry to three equivalent Mg, three equivalent Nd, and three equivalent Pt atoms. All Nd–Nd bond lengths are 3.69 Å. All Nd–Pt bond lengths are 2.94 Å. In the second Nd site, Nd is bonded in a bent 150 degrees geometry to two equivalent Mg, four equivalent Nd, and two equivalent Pt atoms. All Nd–Nd bond lengths are 3.79 Å. Both Nd–Pt bond lengths are 2.95 Å. In the third Nd site, Nd is bonded in a 4-coordinate geometry to two equivalent Mg, ten Nd, and two equivalent Pt atoms. All Nd–Nd bond lengths are 3.72 Å. Both Nd–Pt bond lengths are 3.69 Å. Pt is bonded in a 6-coordinate geometry to nine Nd atoms.
