Abstract
In the title compound, C5H12NO2+.C4H3O4-, the amino acid exists in the cati
onic form and the maleic acid molecule in the mono-ionized state. The intra
molecular 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-valin
ium cations form alternating hydrophobic columns down the a axis. The cryst
al structure is stabilized by O-H . . .O and N-H . . .O hydrogen bonds.
