The title compound, Na+center dot 3C(2)H(6)NO(2)(+)center dot 2SiF(6)(2-)center dot 3C(2)H(5)NO(2), arose from an unexpected reaction of glycine and HF with the glass container. It is an unusual hybrid organic-inorganic network built up from chains of vertex-sharing NaF4O2 and SiF6 octahedra. A pair of glycinium/glycine molecules bridges the chains into a sheet via a centrosymmetric O center dot center dot center dot H center dot center dot center dot O link. The other organic species interact with the network by an extensive N-H center dot center dot center dot F hydrogen-bond network, including bifurcated and trifurcated bonds. Finally, an extremely short C-H center dot center dot center dot O interaction (H center dot center dot center dot O = 2.25 angstrom) is seen in the crystal structure. The Na atom has site symmetry (1) over bar.
