Abstract: In the title compound, C₅H₁₀NO₂⁺·C₂Cl₃O₂^-, the proline molecule exists as a cation with a positively charged amino group and a neutral carboxylic acid group. The trichloroacetic acid molecule is in the anionic state. The 3₁-screw-related proline cations and trichloroacetate anions are linked by N-HO and O-HO hydrogen bonds to form molecular columns along the c axis. No head-to-tail hydrogen bonds are observed.
