Materials Data on Nd2Y by Materials Project
Nd2Y is beta-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Nd is bonded to nine equivalent Nd and three equivalent Y atoms to form NdNd9Y3 cuboctahedra that share corners with six equivalent YNd6Y6 cuboctahedra, corners with nine equivalent NdNd9Y3 cuboctahedra, edges with six equivalent YNd6Y6 cuboctahedra, edges with fifteen equivalent NdNd9Y3 cuboctahedra, faces with seven equivalent YNd6Y6 cuboctahedra, and faces with twelve equivalent NdNd9Y3 cuboctahedra. There are six shorter (3.65 Å) and three longer (3.75 Å) Nd–Nd bond lengths. All Nd–Y bond lengths are 3.61 Å. Y is bonded to six equivalent Nd and six equivalent Y atoms to form YNd6Y6 cuboctahedra that share corners with six equivalent YNd6Y6 cuboctahedra, corners with twelve equivalent NdNd9Y3 cuboctahedra, edges with six equivalent YNd6Y6 cuboctahedra, edges with twelve equivalent NdNd9Y3 cuboctahedra, faces with six equivalent YNd6Y6 cuboctahedra, and faces with fourteen equivalent NdNd9Y3 cuboctahedra. All Y–Y bond lengths are 3.65 Å.
