Summary: | The title compound, C6H14N22+·2C7H4ClO2−, contains trimeric units linked by N—H...O hydrogen bonds. The carboxylate groups of the 2-chlorobenzoate anions form dihedral angles of 66.1 (1) and 76.1 (1)° with the respective chlorobenzene rings to which they are bound. The hydrogen-bonded trimers are arranged in layers in the (200) planes and the chlorobenzoate anions form edge-to-face interactions between layers, with dihedral angles of 61.9 (1) and 49.8 (1)° and centroid–centroid distances of 4.85 (1) and 4.65 (1) Å, respectively, for two crystallographically distinct interactions.
