Materials Data on LiPt7 by Materials Project
LiPt7 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Li1+ is bonded to twelve equivalent Pt+0.14- atoms to form LiPt12 cuboctahedra that share corners with twelve equivalent LiPt12 cuboctahedra and faces with six equivalent PtPt12 cuboctahedra. All Li–Pt bond lengths are 2.78 Å. There are two inequivalent Pt+0.14- sites. In the first Pt+0.14- site, Pt+0.14- is bonded to twelve equivalent Pt+0.14- atoms to form PtPt12 cuboctahedra that share corners with twelve equivalent PtPt12 cuboctahedra and faces with six equivalent LiPt12 cuboctahedra. All Pt–Pt bond lengths are 2.78 Å. In the second Pt+0.14- site, Pt+0.14- is bonded in a distorted linear geometry to two equivalent Li1+ and two equivalent Pt+0.14- atoms.
