Abstract: In the title compound, C₅H₁₂NO₂⁺·C₄H₃O₄^-, the amino acid exists in the cationic form and the maleic acid molecule in the mono-ionized state. The intramolecular hydrogen bond observed between atoms O3 and O5 in the semimaleate anion is found to be asymmetric. The non-polar side chains of the DL-valinium cations form alternating hydrophobic columns down the a axis. The crystal structure is stabilized by O-HO and N-HO hydrogen bonds.
