Na2GeF6 is zeta iron carbide-derived structured and crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Na1+ is bonded to six F1- atoms to form NaF6 octahedra that share corners with four equivalent GeF6 octahedra, an edgeedge with one GeF6 octahedra, and edges with three equivalent NaF6 octahedra. The corner-sharing octahedra tilt angles range from 41–45°. There are a spread of Na–F bond distances ranging from 2.32–2.39 Å. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to six F1- atoms to form GeF6 octahedra that share corners with twelve equivalent NaF6 octahedra. The corner-sharing octahedra tilt angles range from 41–45°. All Ge–F bond lengths are 1.84 Å. In the second Ge4+ site, Ge4+ is bonded to six equivalent F1- atoms to form GeF6 octahedra that share edges with six equivalent NaF6 octahedra. All Ge–F bond lengths are 1.84 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one Ge4+ atom. In the second F1- site, F1- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one Ge4+ atom. In the third F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Na1+ and one Ge4+ atom.
