The material described by PtY2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to four equivalent Pt(1) atoms to form a mixture of corner and edge-sharing YPt4 tetrahedra. In the second Y site, Y(2) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. Pt(1) is bonded in a 7-coordinate geometry to three equivalent Y(2) and four equivalent Y(1) atoms. is represented by the CIF card [CIF]
