The compound described by Pt2Si is Fluorite structured and crystallizes in the tetragonal I4/mmm space group. Pt(1) is bonded to four equivalent Si(1) atoms to form a mixture of edge and corner-sharing PtSi4 tetrahedra. Si(1) is bonded in a body-centered cubic geometry to eight equivalent Pt(1) atoms. is represented by the CIF file [CIF]
