Abstract: In the title compound, CH3NH3+·BF4-·C12H24O6, the methylammonium cation makes three N-HO hydrogen bonds to the 18-crown-6 molecule. The -NH3+ and -CH3 groups of the cation adopt a staggered conformation. The F atoms of the tetrafluoridoborate anion are disordered over two sets of sites in a 0.519 (11):0.481 (11) ratio. Weak C-HF interactions occur in the crystal, which possibly correlate with the anion disorder.
