N-(2,5-Dichlorophenyl)succinamic acid

Abstract

In the title compound, C10H9Cl2NO3, the conformation of the N—H bond in the amide segment is syn with respect to the ortho-Cl atom and anti to the meta-Cl atom of the benzene ring. In the crystal, intermolecular O—H...O and N—H...O hydrogen bonds pack the molecules into two types of chains along the a and b axes, respectively, leading to an overall sheet structure. The acid group in the side chain is disordered and was refined using a split model with site-occupation factors of 0.60:0.40.
