Materials Data on LaY by Materials Project

Abstract

LaY crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. La is bonded to six equivalent La and six equivalent Y atoms to form LaLa6Y6 cuboctahedra that share corners with twelve equivalent LaLa6Y6 cuboctahedra, edges with twelve equivalent LaLa6Y6 cuboctahedra, edges with twelve equivalent YLa6Y6 cuboctahedra, faces with six equivalent LaLa6Y6 cuboctahedra, and faces with twelve equivalent YLa6Y6 cuboctahedra. All La–La bond lengths are 3.68 Å. All La–Y bond lengths are 3.66 Å. Y is bonded to six equivalent La and six equivalent Y atoms to form YLa6Y6 cuboctahedra that share corners with eighteen equivalent YLa6Y6 cuboctahedra, edges with six equivalent YLa6Y6 cuboctahedra, edges with twelve equivalent LaLa6Y6 cuboctahedra, faces with eight equivalent YLa6Y6 cuboctahedra, and faces with twelve equivalent LaLa6Y6 cuboctahedra. All Y–Y bond lengths are 3.68 Å.
