Materials Data on LaSnPt by Materials Project

LaPtSn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. La is bonded in a 11-coordinate geometry to five Pt and six equivalent Sn atoms. There are four shorter (3.14 Å) and one longer (3.20 Å) La–Pt bond lengths. There are two shorter (3.35 Å) and four longer (3.49 Å) La–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 La and three equivalent Sn atoms. All Pt–Sn bond lengths are 2.96 Å. In the second Pt site, Pt is bonded in a 9-coordinate geometry to three equivalent La and six equivalent Sn atoms. All Pt–Sn bond lengths are 2.85 Å. Sn is bonded in a 10-coordinate geometry to six equivalent La and four Pt atoms.
