In the cation of the title compound, C10H13N2O+·I−, all non-H atoms, with the exception of the O atom, are essentially coplanar, tattoos with a maximum deviation of 0.04 (1) Å.In the crystal, the cations and anions are arranged in layers parallel to (100).The cations are connected to the anions via an O—H.I hydrogen bond and there are significant π–π stacking interactions between cation layers, with centroid–centroid distances in the range 3.

606 (5)–3.630 (5) Å.A weak Clear RP Parts intramolecular C—H.O hydrogen bond is also observed.The crystal studied was an inversion twin with refined components of 0.
