Solvent-free (2S)-methyl 2-ammonio-3-(4-hydroxyphenyl)propionate chloride, C10H14NO3+.Cl-, (I), and its methanol solvate, C10H14NO3+.Cl-.CH3OH, (II), are obtained from different solvents: crystallization from ethanol or propan-2-ol gives the same solvent-free crystals of (I) in both cases, while crystals of (II) were obtained by crystallization from methanol. The structure of (I) is characterized by the presence of two-dimensional layers linked together by N-H...Cl and O-H...Cl hydrogen bonds and also by C-H...O contacts. Incorporation of the methanol solvent molecule in (II) introduces additional O-H...O hydrogen bonds linking the two-dimensional layers, resulting in the formation of a three-dimensional network.
