N-(3-Chloro-4-methyl-phen-yl)succinamic acid.

ABSTRACT: In the crystal structure of the title compound, C(11)H(12)ClNO(3), the asymmetric unit contains two independent mol-ecules. 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 -CH(2) 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, mol-ecules are packed into sheets parallel to the (11-3) plane through O-H?O and N-H?O hydrogen bonds.
