Abstract

Nd2Ni7 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Nd sites. In the first Nd site, Nd is bonded in a 12-coordinate geometry to twelve Ni atoms. There are a spread of Nd–Ni bond distances ranging from 2.88–3.22 Å. In the second Nd site, Nd is bonded in a 6-coordinate geometry to eighteen Ni atoms. There are a spread of Nd–Ni bond distances ranging from 2.90–3.30 Å. There are five inequivalent Ni sites. In the first Ni site, Ni is bonded in a 12-coordinate geometry to three equivalent Nd and six Ni atoms. There are three shorter (2.45 Å) and three longer (2.48 Å) Ni–Ni bond lengths. In the second Ni site, Ni is bonded to six equivalent Nd and six equivalent Ni atoms to form NiNd6Ni6 cuboctahedra that share corners with twelve equivalent NiNd5Ni7 cuboctahedra, edges with six equivalent NiNd6Ni6 cuboctahedra, and faces with eighteen equivalent NiNd5Ni7 cuboctahedra. All Ni–Ni bond lengths are 2.58 Å. In the third Ni site, Ni is bonded to four equivalent Nd and eight Ni atoms to form NiNd4Ni8 cuboctahedra that share corners with sixteen NiNd5Ni7 cuboctahedra, edges with ten NiNd5Ni7 cuboctahedra, and faces with ten NiNd4Ni8more »« less
