The crystal structure described by Li2PtF6 is Hydrophilite-derived structured and crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form LiF6 octahedra that share corners with four equivalent Li(1)F6 octahedra, corners with four equivalent Pt(1)F6 octahedra,  an edgeedge with one Li(1)F6 octahedra, and  an edgeedge with one Pt(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 48-51°. Pt(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form PtF6 octahedra that share corners with eight equivalent Li(1)F6 octahedra and edges with two equivalent Li(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 48-50°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one Pt(1) atom. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one Pt(1) atom. In the third F site, F(3) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one Pt(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
