Materials Data on YSnPt2 by Materials Project

YPt2Sn crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Y is bonded in a 6-coordinate geometry to six equivalent Pt and six equivalent Sn atoms. All Y–Pt bond lengths are 2.89 Å. All Y–Sn bond lengths are 3.48 Å. Pt is bonded in a 8-coordinate geometry to three equivalent Y, one Pt, and four equivalent Sn atoms. The Pt–Pt bond length is 2.70 Å. There are one shorter (2.79 Å) and three longer (3.10 Å) Pt–Sn bond lengths. Sn is bonded in a 2-coordinate geometry to six equivalent Y and eight equivalent Pt atoms.

Materials Data on YSnPt2 by Materials Project

YPt2Sn crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Y is bonded in a 8-coordinate geometry to eight equivalent Pt atoms. There are six shorter (3.01 Å) and two longer (3.12 Å) Y–Pt bond lengths. Pt is bonded in a 8-coordinate geometry to four equivalent Y and three equivalent Sn atoms. All Pt–Sn bond lengths are 2.76 Å. Sn is bonded to six equivalent Pt atoms to form distorted edge-sharing SnPt6 cuboctahedra.
