Materials Data on Sn3Pt2 by Materials Project
Pt2Sn3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pt is bonded in a distorted body-centered cubic geometry to one Pt and seven Sn atoms. The Pt–Pt bond length is 2.82 Å. There are a spread of Pt–Sn bond distances ranging from 2.72–2.91 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded to four equivalent Pt atoms to form a mixture of distorted edge and corner-sharing SnPt4 tetrahedra. In the second Sn site, Sn is bonded in a 6-coordinate geometry to six equivalent Pt atoms.
