The material structure described by GdPtSi is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. Gd(1) is bonded to six equivalent Pt(1) and six equivalent Si(1) atoms to form a mixture of edge and face-sharing GdSi6Pt6 cuboctahedra. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Gd(1) and three equivalent Si(1) atoms. Si(1) is bonded in a distorted trigonal planar geometry to six equivalent Gd(1) and three equivalent Pt(1) atoms. is represented by the CIF file [CIF]
