In the title inorganic molecular salt, (N2H5)2SiF6, the silicon atom at the centre of the slightly distorted SiF6 octahedron [range of Si—F distances = 1.6777 (4)–1.7101 (4) Å] lies on a crystallographic inversion centre. In the crystal, the ions are connected by N—H...N and N—H...F hydrogen bonds; the former link the cations into [010] chains and the latter (some of which are bifurcated or trifurcated) link the ions into a three-dimensional network. The two-dimensional fingerprint plots show that F...H/H...F interactions dominate the Hirshfeld surface (75.5%) followed by H...H (13.6%) and N...H/H...N (8.4%) whereas F...F (1.9%) and F...N/N...F (0.6%) have negligible percentages. The title compound is isostructural with its germanium-containing analogue.
