The compound described by Y5Pt4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded to two equivalent Pt(1), two equivalent Pt(2), and two equivalent Pt(3) atoms to form distorted corner-sharing YPt6 octahedra. The corner-sharing octahedral tilt angles range from 50-53°. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to one Pt(1), two equivalent Pt(2), and three equivalent Pt(3) atoms. In the third Y site, Y(3) is bonded in a 7-coordinate geometry to one Pt(2), two equivalent Pt(1), and four equivalent Pt(3) atoms. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to two equivalent Y(1), two equivalent Y(2), four equivalent Y(3), and one Pt(2) atom. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to two equivalent Y(1), two equivalent Y(3), four equivalent Y(2), and one Pt(1) atom. In the third Pt site, Pt(3) is bonded in a 8-coordinate geometry to one Y(1), three equivalent Y(2), and four equivalent Y(3) atoms. is represented by the CIF file [CIF]
