YbAuSi is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. Yb(1) is bonded to six equivalent Au(1) and six equivalent Si(1) atoms to form a mixture of edge and face-sharing YbSi6Au6 cuboctahedra. Au(1) is bonded in a 9-coordinate geometry to six equivalent Yb(1) and three equivalent Si(1) atoms. Si(1) is bonded in a distorted trigonal planar geometry to six equivalent Yb(1) and three equivalent Au(1) atoms.
