Pt3Y is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Y is bonded to twelve equivalent Pt atoms to form a mixture of face and corner-sharing YPt12 cuboctahedra. All Y–Pt bond lengths are 2.92 Å. Pt is bonded in a distorted square co-planar geometry to four equivalent Y atoms.
YPt2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Y is bonded in a 12-coordinate geometry to twelve equivalent Pt atoms. All Y–Pt bond lengths are 3.20 Å. Pt is bonded to six equivalent Y and six equivalent Pt atoms to form a mixture of edge, corner, and face-sharing PtY6Pt6 cuboctahedra. All Pt–Pt bond lengths are 2.72 Å.
Y3Pt is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a distorted bent 120 degrees geometry to two equivalent Pt atoms. There are one shorter (2.82 Å) and one longer (2.89 Å) Y–Pt bond lengths. In the second Y site, Y is bonded in a 2-coordinate geometry to three equivalent Pt atoms. There are a spread of Y–Pt bond distances ranging from 2.88–3.40 Å. Pt is bonded in a 6-coordinate geometry to eight Y atoms.
PtY crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Y is bonded in a 7-coordinate geometry to seven equivalent Pt atoms. There are a spread of Y–Pt bond distances ranging from 2.90–3.03 Å. Pt is bonded in a 7-coordinate geometry to seven equivalent Y atoms.
