Abstract: In the title salt, C₁₂H₂₀NO⁺·CH₃SO₃^-, the [1-(1-adamantylamino)ethylidene]oxonium cations and methanesulfonate anions are linked into chains along the a axis via O-HO and N-HO hydrogen bonds. All non-H atoms of the acetamido group are essentially planar, with a maximum deviation of 0.0085 (12) Å. In comparison with related structures, the carbonyl C=O bond is slightly elongated [1.249 (2) Å], whereas the amide C-N bond is shortened [1.292 (2) Å].
