The structure described by Y2(PtSi)3 crystallizes in the tetragonal P4/mmm space group. Y(1) is bonded to four equivalent Y(1), one Pt(1), and one Si(1) atom to form a mixture of distorted corner and edge-sharing YY4SiPt octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted linear geometry to one Y(1) and one Si(2) atom. In the second Pt site, Pt(2) is bonded in a distorted linear geometry to two equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a distorted linear geometry to one Y(1) and one Pt(2) atom. In the second Si site, Si(2) is bonded in a linear geometry to two equivalent Pt(1) atoms. is represented by the CIF file [CIF]
