UAuSi crystallizes in the hexagonal P-6m2 space group. U(1) is bonded to six equivalent Au(1) and six equivalent Si(1) atoms to form a mixture of face and edge-sharing USi6Au6 cuboctahedra. Au(1) is bonded in a distorted trigonal planar geometry to six equivalent U(1) and three equivalent Si(1) atoms. Si(1) is bonded in a distorted trigonal planar geometry to six equivalent U(1) and three equivalent Au(1) atoms.
