WAu3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. W(1) is bonded to four equivalent Au(2) and eight equivalent Au(1) atoms to form WAu12 cuboctahedra that share corners with four equivalent W(1)Au12 cuboctahedra, corners with eight equivalent Au(2)W4Au8 cuboctahedra, edges with eight equivalent W(1)Au12 cuboctahedra, edges with sixteen equivalent Au(1)W4Au8 cuboctahedra, faces with four equivalent W(1)Au12 cuboctahedra, faces with six equivalent Au(2)W4Au8 cuboctahedra, and faces with eight equivalent Au(1)W4Au8 cuboctahedra. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded to four equivalent W(1), four equivalent Au(1), and four equivalent Au(2) atoms to form distorted AuW4Au8 cuboctahedra that share corners with twelve equivalent Au(1)W4Au8 cuboctahedra, edges with eight equivalent W(1)Au12 cuboctahedra, edges with eight equivalent Au(1)W4Au8 cuboctahedra, edges with eight equivalent Au(2)W4Au8 cuboctahedra, faces with four equivalent W(1)Au12 cuboctahedra, faces with four equivalent Au(2)W4Au8 cuboctahedra, and faces with ten equivalent Au(1)W4Au8 cuboctahedra. In the second Au site, Au(2) is bonded to four equivalent W(1) and eight equivalent Au(1) atoms to form AuW4Au8 cuboctahedra that share corners with four equivalent Au(2)W4Au8 cuboctahedra, corners with eight equivalent W(1)Au12 cuboctahedra, edges with eight equivalent Au(2)W4Au8 cuboctahedra, edges with sixteen equivalent Au(1)W4Au8 cuboctahedra, faces with four equivalent Au(2)W4Au8 cuboctahedra, faces with six equivalent W(1)Au12 cuboctahedra, and faces with eight equivalent Au(1)W4Au8 cuboctahedra.
