UAuSb2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. U(1) is bonded to four equivalent Au(1), four equivalent Sb(1), and four equivalent Sb(2) atoms to form USb8Au4 cuboctahedra that share corners with four equivalent U(1)Sb8Au4 cuboctahedra, edges with eight equivalent U(1)Sb8Au4 cuboctahedra, edges with eight equivalent Au(1)U4Sb4Au4 cuboctahedra, faces with four equivalent U(1)Sb8Au4 cuboctahedra, and faces with four equivalent Au(1)U4Sb4Au4 cuboctahedra. Au(1) is bonded to four equivalent U(1), four equivalent Au(1), and four equivalent Sb(1) atoms to form distorted AuU4Sb4Au4 cuboctahedra that share corners with four equivalent Au(1)U4Sb4Au4 cuboctahedra, edges with eight equivalent U(1)Sb8Au4 cuboctahedra, faces with four equivalent U(1)Sb8Au4 cuboctahedra, and faces with eight equivalent Au(1)U4Sb4Au4 cuboctahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Au(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Sb(2) atoms.
