The material structure described by Pt3Si crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a water-like geometry to four equivalent Pt(2) and two equivalent Si(1) atoms. In the second Pt site, Pt(2) is bonded to eight equivalent Pt(1) and four equivalent Si(1) atoms to form a mixture of distorted corner and face-sharing PtSi4Pt8 cuboctahedra. Si(1) is bonded in a distorted body-centered cubic geometry to four equivalent Pt(1) and four equivalent Pt(2) atoms. is represented by the CIF card [CIF]
