✦ Synopsis
In the crystal structure of 2,4,6-trimethylanilinium iodide, C 9 H 11 NH 3 + ÁI À , both ions are situated on mirror planes. The trimethylanilinium ions stack head-to-tail with nointeractions. The ammonium cations and I À anions interact via hydrogen bonds, forming ladder-like columns parallel to the b axis. The structure is compared to the related anilinium iodide.

The title compound, C~13~H~15~N~2~ ^+^·C~14~H~11~O~3~ ^−^, is a molecular salt in which the conformation of the anion is stabilized by an intramolecular O—H...O interaction. The species are linked by an N—H...O bond and further hydrogen bonds lead to infinite one-dimensional chains along [010].
The asymmetric unit of the title salt, C~12~H~13~N~2~O^+^·C~14~H~11~O~3~ ^−^, contains two cations and two anions, in which cation–anion pairs are linked together by an N—H...O hydrogen bond. An intramolecular O—H...O hydrogen bond occurs within each anion and forms an __S__(5) ring. These component
