Abstract:
In the title compound, C(11)H(12)N(2)O(2)·C(7)H(5)NO(4)·C(2)H(6)O, 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 mol-ecules and pyridine-2,4-dicarb-oxylic acid mol-ecules are linked through strong inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, forming layers parallel to (100). The layers are linked through the ethanol mol-ecules via somewhat weaker inter-molecular 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 inter-actions between the aromatic rings are also present.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
