The material described by Na2PtF6 is Hydrophilite-derived structured and crystallizes in the trigonal P321 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form NaF6 octahedra that share corners with four equivalent Pt(2)F6 octahedra, corners with six equivalent Na(2)F6 octahedra, and  an edgeedge with one Pt(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 46-57°. In the second Na site, Na(2) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form NaF6 octahedra that share corners with two equivalent Pt(1)F6 octahedra, corners with six equivalent Na(1)F6 octahedra, and edges with two equivalent Pt(2)F6 octahedra. The corner-sharing octahedral tilt angles range from 50-57°. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to six equivalent F(1) atoms to form PtF6 octahedra that share corners with six equivalent Na(2)F6 octahedra and edges with three equivalent Na(1)F6 octahedra. The corner-sharing octahedral tilt angles are 50°. In the second Pt site, Pt(2) is bonded to three equivalent F(2) and three equivalent F(3) atoms to form PtF6 octahedra that share corners with six equivalent Na(1)F6 octahedra and edges with three equivalent Na(2)F6 octahedra. The corner-sharing octahedral tilt angles range from 46-47°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to one Na(1), one Na(2), and one Pt(1) atom. In the second F site, F(2) is bonded in a trigonal planar geometry to one Na(1), one Na(2), and one Pt(2) atom. In the third F site, F(3) is bonded in a trigonal planar geometry to one Na(1), one Na(2), and one Pt(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
