Figure 2 Different motives of C—H⋯F contacts and O—H⋯F H-bonds in (I) with labeling. H-atoms of methyl groups are omitted for clarity. C—H⋯F contacts and H-bonds are depicted as dotted lines. Symmetry codes: (iv) –x, –y, –z; (vii) –y, x–y, z; (viii) y, –x + y, –z; (x) –x + y, –x, z; (xi) x–y, x, –z; (xxii) –x + 1, –y + 1, z; (xxiii) x–y, x, z; (xxiv) –x + 1, –x + y+1, –z + $[{1\over 2}]$ ; (xxv) x, x–y + 1, –z–1/2; (xxvi) x, x–y + 1, z–1/2. (a) The rod-type assembling of the imidazolium cations and the [SiF₆^2–] dianions located at the 3.2 inversion centres. A view along the a-axis. H⋯F contacts motif $[C_{2}^{2}]$ (7)[3 $[R_{4}^{4}]$ (14)]. (b) Linking of the rod ensembles by the [SiF₆^2–] dianions located at the 6/m inversion centres. A view along the c-axis. Methanol molecules are omitted for clarity. Only one of two disordered [SiF₆^2–] dianions is depicted. All shown imidazolium cations belong to different rod-type aggregates. H⋯F contacts motif D₂²(4). (c) H-bonding between the twofold disordered [SiF₆^2–] dianions located at the 6/m inversion centres and the 12-fold disordered methanol molecules. A view along the (3, 1, 0) direction. Only crystallographically independent atoms are labeled. H-bonds motif either D₂²(4) or D.
