Bis(2-amino-4,5-dimethylanilinium chloride) 4,5-dimethylbenzene-1,2-diamine monohydrate

Abstract

The title compound, 2C8H13N2+·2Cl−·C8H12N2·H2O, is a hydrated 2:1 cocrystal of the 2-amino-4,5-dimethylanilinium chloride salt and the 4,5-dimethylbenzene-1,2-diamine free base. An intramolecular N—H...N hydrogen bond occurs in one of the organic molecules. In the crystal structure, the components are linked by N—H...Cl, N—H...N, N—H...O and O—H...Cl hydrogen bonds into a layered motif.
