Materials Data on ThSiAu by Materials Project
ThAuSi crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Th is bonded to six equivalent Au and six equivalent Si atoms to form a mixture of edge and face-sharing ThSi6Au6 cuboctahedra. All Th–Au bond lengths are 3.25 Å. All Th–Si bond lengths are 3.25 Å. Au is bonded in a distorted trigonal planar geometry to six equivalent Th and three equivalent Si atoms. All Au–Si bond lengths are 2.50 Å. Si is bonded in a distorted trigonal planar geometry to six equivalent Th and three equivalent Au atoms.
