Part of the composite inorganic/organic (001) sheet structure in (I), with the inorganic species shown as polyhedra. The NaF2O4 and SiF6 octahedra are light and dark, respectively. The symmetric O6⋯H⋯O6i link is indicated. C-bound H atoms have been omitted for clarity. [Symmetry codes: (i) −x, 1 − y, −z; (ii) x − 1, y, z.] |
