Materials Data on YbSnPt by Materials Project
YbPtSn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Yb is bonded in a 11-coordinate geometry to five Pt and six equivalent Sn atoms. All Yb–Pt bond lengths are 3.05 Å. There are two shorter (3.22 Å) and four longer (3.36 Å) Yb–Sn bond lengths. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a 9-coordinate geometry to six equivalent Yb and three equivalent Sn atoms. All Pt–Sn bond lengths are 2.81 Å. In the second Pt site, Pt is bonded in a 9-coordinate geometry to three equivalent Yb and six equivalent Sn atoms. All Pt–Sn bond lengths are 2.82 Å. Sn is bonded in a 10-coordinate geometry to six equivalent Yb and four Pt atoms.
