Crystal structure of 4-(2-hydroxy-3-methoxybenzylamino)benzoic acid dimethylformamide monosolvate monohydrate

Abstract

The title compound, C15H15NO4·C3H7NO·H2O, a secondary amine molecule, is accompanied by one equivalent of water and one equivalent of dimethylformamide (DMF) as solvents. The molecule is non-planar, with a Caryl—CH2—NH—Caryl torsion angle of −66.3 (3)°. In the crystal, O—H...O and N—H...O hydrogen-bonding interactions between the amine molecules and the two types of solvent molecule result in the formation of a layered structure extending parallel to (010).
