The crystal structure described by ThPtSi is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. Th(1) is bonded to six Pt(1,1) and six equivalent Si(1) atoms to form a mixture of edge and face-sharing ThSi6Pt6 cuboctahedra. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted trigonal planar geometry to six equivalent Th(1) and three equivalent Si(1) atoms. In the second Pt site, Pt(1) is bonded in a distorted trigonal planar geometry to six equivalent Th(1) and three equivalent Si(1) atoms. Si(1) is bonded in a distorted trigonal planar geometry to six equivalent Th(1) and three Pt(1,1) atoms. is represented by the CIF file [CIF]
