Materials Data on Nd2MgNi2 by Materials Project
Nd2Ni2Mg crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Mg is bonded to eight equivalent Nd and four equivalent Ni atoms to form a mixture of distorted corner and face-sharing MgNd8Ni4 cuboctahedra. All Mg–Nd bond lengths are 3.38 Å. All Mg–Ni bond lengths are 2.99 Å. Nd is bonded in a 6-coordinate geometry to four equivalent Mg and six equivalent Ni atoms. There are two shorter (2.92 Å) and four longer (2.96 Å) Nd–Ni bond lengths. Ni is bonded in a 9-coordinate geometry to two equivalent Mg, six equivalent Nd, and one Ni atom. The Ni–Ni bond length is 2.53 Å.
