Materials Data on Ce3Al by Materials Project

Abstract

Ce3Al is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ce is bonded to eight equivalent Ce and four equivalent Al atoms to form distorted CeCe8Al4 cuboctahedra that share corners with twelve equivalent CeCe8Al4 cuboctahedra, edges with eight equivalent AlCe12 cuboctahedra, edges with sixteen equivalent CeCe8Al4 cuboctahedra, faces with four equivalent AlCe12 cuboctahedra, and faces with fourteen equivalent CeCe8Al4 cuboctahedra. All Ce–Ce bond lengths are 3.32 Å. All Ce–Al bond lengths are 3.32 Å. Al is bonded to twelve equivalent Ce atoms to form AlCe12 cuboctahedra that share corners with twelve equivalent AlCe12 cuboctahedra, edges with twenty-four equivalent CeCe8Al4 cuboctahedra, faces with six equivalent AlCe12 cuboctahedra, and faces with twelve equivalent CeCe8Al4 cuboctahedra.
