Abstract: The title compound, 2-hydroxy-2-(4-hydroxyphenyl)-N-methylethanaminium chloride, C9H14NO2+·Cl-, has been isolated for the first time from the genus Harrisonia. Its structure is stabilized by extensive intra- and intermolecular hydrogen bonds of type O-H...O, N-H...O, N-H...Cl and C-H...Cl, resulting in a three-dimensional network. Additional weak [pi]-[pi] stacking interactions between adjacent molecules further stabilize the crystal structure.
