Abstract
In the title compound, C3H8NO2+·C4H3O4−, the alanine molecule exists in the cationic form and the maleic acid molecule in the mono-ionized state. A head-to-tail hydrogen bond is observed between the amino acid molecules. There are no direct hydrogen-bonded interactions between the semimaleate anions. The overall aggregation pattern is similar to that observed in the l-alanine-oxalic acid complex.
