Au3Co is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Co(1) is bonded to twelve equivalent Au(1) atoms to form CoAu12 cuboctahedra that share corners with twelve equivalent Co(1)Au12 cuboctahedra, edges with twenty-four equivalent Au(1)Co4Au8 cuboctahedra, faces with six equivalent Co(1)Au12 cuboctahedra, and faces with twelve equivalent Au(1)Co4Au8 cuboctahedra. Au(1) is bonded to four equivalent Co(1) and eight equivalent Au(1) atoms to form distorted AuCo4Au8 cuboctahedra that share corners with twelve equivalent Au(1)Co4Au8 cuboctahedra, edges with eight equivalent Co(1)Au12 cuboctahedra, edges with sixteen equivalent Au(1)Co4Au8 cuboctahedra, faces with four equivalent Co(1)Au12 cuboctahedra, and faces with fourteen equivalent Au(1)Co4Au8 cuboctahedra.
