%X The structure of the title salt, 3(C<sub>4</sub>H<sub>7</sub>N<sub>2</sub><sup>+</sup>)·(C<sub>9</sub>H<sub>5</sub>O<sub>6</sub><sup>−</sup>)·( C<sub>9</sub>H<sub>4</sub>O<sub>6</sub><sup>2−</sup>), referred to as compound 1, is reported. This compound consists of three 2-methyl-imidazolium cations and both a single and a doubly deprotonated form of trimesic acid as anions. A detailed analysis of the bond lengths and angles reveals both differences and similarities between compound 1 and the previously reported 2-methyl-1H-imidazol-3-ium 3,5-dicarboxybenzoate structure, as well as the neutral counterpart of the ions. Examination of the crystal packing shows the formation of infinite chains by the anions, which, along with the cations, forms zigzag planes parallel to the ab plane. The packing interactions are primarily driven by π – π interactions and hydrogen bonding between anions.
