Au3Ag is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded to four equivalent Au(1), four equivalent Au(2), and four equivalent Ag(1) atoms to form distorted AuAg4Au8 cuboctahedra that share corners with twelve equivalent Au(1)Ag4Au8 cuboctahedra, edges with eight equivalent Au(1)Ag4Au8 cuboctahedra, edges with eight equivalent Au(2)Ag4Au8 cuboctahedra, edges with eight equivalent Ag(1)Au12 cuboctahedra, faces with four equivalent Au(2)Ag4Au8 cuboctahedra, faces with four equivalent Ag(1)Au12 cuboctahedra, and faces with ten equivalent Au(1)Ag4Au8 cuboctahedra. In the second Au site, Au(2) is bonded to eight equivalent Au(1) and four equivalent Ag(1) atoms to form distorted AuAg4Au8 cuboctahedra that share corners with four equivalent Au(2)Ag4Au8 cuboctahedra, corners with eight equivalent Ag(1)Au12 cuboctahedra, edges with eight equivalent Au(2)Ag4Au8 cuboctahedra, edges with sixteen equivalent Au(1)Ag4Au8 cuboctahedra, faces with four equivalent Au(2)Ag4Au8 cuboctahedra, faces with six equivalent Ag(1)Au12 cuboctahedra, and faces with eight equivalent Au(1)Ag4Au8 cuboctahedra. Ag(1) is bonded to four equivalent Au(2) and eight equivalent Au(1) atoms to form AgAu12 cuboctahedra that share corners with four equivalent Ag(1)Au12 cuboctahedra, corners with eight equivalent Au(2)Ag4Au8 cuboctahedra, edges with eight equivalent Ag(1)Au12 cuboctahedra, edges with sixteen equivalent Au(1)Ag4Au8 cuboctahedra, faces with four equivalent Ag(1)Au12 cuboctahedra, faces with six equivalent Au(2)Ag4Au8 cuboctahedra, and faces with eight equivalent Au(1)Ag4Au8 cuboctahedra.
