The compound described by Pt2Si3 crystallizes in the hexagonal P6_3/mmc space group. Pt(1) is bonded in a 7-coordinate geometry to three equivalent Si(2) and four equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded to four equivalent Pt(1) atoms to form a mixture of corner and edge-sharing SiPt4 tetrahedra. In the second Si site, Si(2) is bonded in a 6-coordinate geometry to six equivalent Pt(1) atoms. is represented by the CIF file [CIF]
