The material structure described by Au3Ag is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Au(1) is bonded to eight equivalent Au(1) and four equivalent Ag(1) atoms to form distorted AuAg4Au8 cuboctahedra that share corners with four equivalent Ag(1)Au12 cuboctahedra, corners with fourteen equivalent Au(1)Ag4Au8 cuboctahedra, edges with six equivalent Ag(1)Au12 cuboctahedra, edges with twelve equivalent Au(1)Ag4Au8 cuboctahedra, faces with four equivalent Ag(1)Au12 cuboctahedra, and faces with sixteen equivalent Au(1)Ag4Au8 cuboctahedra. Ag(1) is bonded to twelve equivalent Au(1) atoms to form AgAu12 cuboctahedra that share corners with six equivalent Ag(1)Au12 cuboctahedra, corners with twelve equivalent Au(1)Ag4Au8 cuboctahedra, edges with eighteen equivalent Au(1)Ag4Au8 cuboctahedra, faces with eight equivalent Ag(1)Au12 cuboctahedra, and faces with twelve equivalent Au(1)Ag4Au8 cuboctahedra. is represented by the CIF file [CIF]
