LiPt7 crystallizes in the cubic Fm-3m space group. Li(1) is bonded to twelve equivalent Pt(2) atoms to form LiPt12 cuboctahedra that share corners with twelve equivalent Li(1)Pt12 cuboctahedra and faces with six equivalent Pt(1)Pt12 cuboctahedra. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to twelve equivalent Pt(2) atoms to form PtPt12 cuboctahedra that share corners with twelve equivalent Pt(1)Pt12 cuboctahedra and faces with six equivalent Li(1)Pt12 cuboctahedra. In the second Pt site, Pt(2) is bonded in a distorted linear geometry to two equivalent Li(1) and two equivalent Pt(1) atoms.
