Au3Cd 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(2) and four equivalent Cd(1) atoms to form distorted AuCd4Au4 cuboctahedra that share corners with eight equivalent Au(1)Cd4Au4 cuboctahedra, corners with eight equivalent Au(2)Cd4Au8 cuboctahedra, corners with eight equivalent Cd(1)Au12 cuboctahedra, edges with four equivalent Au(2)Cd4Au8 cuboctahedra, edges with four equivalent Cd(1)Au12 cuboctahedra, edges with twelve equivalent Au(1)Cd4Au4 cuboctahedra, and faces with six equivalent Au(1)Cd4Au4 cuboctahedra. In the second Au site, Au(2) is bonded to eight equivalent Au(1) and four equivalent Cd(1) atoms to form distorted AuCd4Au8 cuboctahedra that share corners with four equivalent Au(2)Cd4Au8 cuboctahedra, corners with eight equivalent Cd(1)Au12 cuboctahedra, corners with sixteen equivalent Au(1)Cd4Au4 cuboctahedra, edges with eight equivalent Au(1)Cd4Au4 cuboctahedra, edges with eight equivalent Au(2)Cd4Au8 cuboctahedra, faces with four equivalent Au(2)Cd4Au8 cuboctahedra, and faces with six equivalent Cd(1)Au12 cuboctahedra. Cd(1) is bonded to four equivalent Au(2) and eight equivalent Au(1) atoms to form CdAu12 cuboctahedra that share corners with four equivalent Cd(1)Au12 cuboctahedra, corners with eight equivalent Au(2)Cd4Au8 cuboctahedra, corners with sixteen equivalent Au(1)Cd4Au4 cuboctahedra, edges with eight equivalent Au(1)Cd4Au4 cuboctahedra, edges with eight equivalent Cd(1)Au12 cuboctahedra, faces with four equivalent Cd(1)Au12 cuboctahedra, and faces with six equivalent Au(2)Cd4Au8 cuboctahedra.
