Materials Data on CoAu3 by Materials Project

Abstract

Au3Co is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Co3+ is bonded to twelve equivalent Au1- atoms to form CoAu12 cuboctahedra that share corners with twelve equivalent CoAu12 cuboctahedra, edges with twenty-four equivalent AuCo4Au8 cuboctahedra, faces with six equivalent CoAu12 cuboctahedra, and faces with twelve equivalent AuCo4Au8 cuboctahedra. All Co–Au bond lengths are 2.85 Å. Au1- is bonded to four equivalent Co3+ and eight equivalent Au1- atoms to form distorted AuCo4Au8 cuboctahedra that share corners with twelve equivalent AuCo4Au8 cuboctahedra, edges with eight equivalent CoAu12 cuboctahedra, edges with sixteen equivalent AuCo4Au8 cuboctahedra, faces with four equivalent CoAu12 cuboctahedra, and faces with fourteen equivalent AuCo4Au8 cuboctahedra. All Au–Au bond lengths are 2.85 Å.
