Abstract: In the title compound, C₂H₆NO₂⁺·C₄H₃O₄^-, the glycine molecule exists in the cationic form with a positively charged amino group and an uncharged carboxylic acid group. The maleic acid molecule exists in a mono-ionized state. In the semimaleate ion, an intramolecular OHO hydrogen bond is found to be asymmetric. The glycinium and semimaleate ions aggregate into alternate columns extending along the c axis. A C-HO hydrogen bond is also observed.
