More Information
Summary:The asymmetric unit of the title structure, C 8 H 7 NO 4 ·2C 3 H 7 NO, 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.
