Abstract
The asymmetric unit of the title structure, C8H7NO4·2C3H7NO, contains one 2-aminoterephthalic acid and two N,N-dimethylformamide molecules. Strong O—H⋯O hydrogen bonds between the acidic carboxy H atoms of 2-aminoterephthalic acid and the O atoms of both solvent molecules form linear 1:2 complex units. One H atom of the amine group is involved in intramolecular N—H⋯O hydrogen bonding, whereas the second one takes part in an intermolecular N—H⋯O connection. Furthermore, the crystal is stabilized by weak C—H⋯O hydrogen bonds.
