Abstract

Mg4Nd23Rh7 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded to three equivalent Mg and nine Nd atoms to form face-sharing MgNd9Mg3 cuboctahedra. All Mg–Mg bond lengths are 3.16 Å. There are a spread of Mg–Nd bond distances ranging from 3.44–3.70 Å. In the second Mg site, Mg is bonded to three Mg and nine Nd atoms to form a mixture of face and corner-sharing MgNd9Mg3 cuboctahedra. Both Mg–Mg bond lengths are 3.21 Å. There are a spread of Mg–Nd bond distances ranging from 3.43–3.71 Å. There are nine inequivalent Nd sites. In the first Nd site, Nd is bonded in a 4-coordinate geometry to two equivalent Mg and two Rh atoms. There are one shorter (3.53 Å) and one longer (3.65 Å) Nd–Rh bond lengths. In the second Nd site, Nd is bonded in a 3-coordinate geometry to three equivalent Mg and three equivalent Rh atoms. All Nd–Rh bond lengths are 2.90 Å. In the third Nd site, Nd is bonded in a distorted water-like geometry to one Mg and four Rh atoms. There are two shorter (2.88 Å) and two longer (3.61more »« less
