Materials Data on AlCo3 by Materials Project

Abstract

Co3Al is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Co is bonded to eight equivalent Co and four equivalent Al atoms to form CoAl4Co8 cuboctahedra that share corners with twelve equivalent CoAl4Co8 cuboctahedra, edges with eight equivalent AlCo12 cuboctahedra, edges with sixteen equivalent CoAl4Co8 cuboctahedra, faces with four equivalent AlCo12 cuboctahedra, and faces with fourteen equivalent CoAl4Co8 cuboctahedra. All Co–Co bond lengths are 2.53 Å. All Co–Al bond lengths are 2.53 Å. Al is bonded to twelve equivalent Co atoms to form AlCo12 cuboctahedra that share corners with twelve equivalent AlCo12 cuboctahedra, edges with twenty-four equivalent CoAl4Co8 cuboctahedra, faces with six equivalent AlCo12 cuboctahedra, and faces with twelve equivalent CoAl4Co8 cuboctahedra.
