Materials Data on Y3Al by Materials Project

Abstract

Y3Al is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Y is bonded to eight equivalent Y and four equivalent Al atoms to form YY8Al4 cuboctahedra that share corners with twelve equivalent YY8Al4 cuboctahedra, edges with eight equivalent AlY12 cuboctahedra, edges with sixteen equivalent YY8Al4 cuboctahedra, faces with four equivalent AlY12 cuboctahedra, and faces with fourteen equivalent YY8Al4 cuboctahedra. All Y–Y bond lengths are 3.38 Å. All Y–Al bond lengths are 3.38 Å. Al is bonded to twelve equivalent Y atoms to form AlY12 cuboctahedra that share corners with twelve equivalent AlY12 cuboctahedra, edges with twenty-four equivalent YY8Al4 cuboctahedra, faces with six equivalent AlY12 cuboctahedra, and faces with twelve equivalent YY8Al4 cuboctahedra.
