Description
Summary:In the crystal structure of the title compound, C11H12ClNO3, the asymmetric unit contains two independent molecules. The N—H bond in the amide segment is anti to the meta-Cl atom in the benzene ring, in both molecules. The amide and carboxyl C=O bonds are also anti to each other and anti to the H atoms on the adjacent –CH2 groups. Furthermore, the C=O and O—H bonds of the acid group are in syn positions with respect to each other. The dihedral angles between the benzene ring and the amide group are 40.6 (2) and 44.9 (3)° in the two independent molecules. In the crystal, molecules are packed into sheets parallel to the (11-3) plane through O—H...O and N—H...O hydrogen bonds.
