Abstract

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.
