Abstract
In the title compound, C11H12N2O2·C7H5NO4·C2H6O, the (2S*)-2-amino-3-(1H-indol-3-yl)propionic acid is present in the zwitterionic form. In the crystal structure, 2-amino-3-(1H-indol-3-yl)propionic acid molecules and pyridine-2,4-dicarboxylic acid molecules are linked through strong intermolecular O—H⋯O and N—H⋯O hydrogen bonds, forming layers parallel to (100). The layers are linked through the ethanol molecules via somewhat weaker intermolecular O—H⋯O and N—H⋯O hydrogen bonds, forming thus a three-dimensional network. Weak C—H⋯O and N—H⋯N hydrogen bonding and π–π interactions between the aromatic rings are also present.
