Crystal structure of 2-(4-chloro­benzamido)­benzoic acid

In the title mol­ecule, C(14)H(10)ClNO(3), the amide C=O bond is anti to the o-carb­oxy substituent in the adjacent benzene ring, a conformation that facilitates the formation of an intra­molecular amide-N—H⋯O(carbon­yl) hydrogen bond that closes an S(6) loop. The central amide segment is twisted away from the carb­oxy- and chloro-substituted benzene rings by 13.93 (17) and 15.26 (15)°, respectively. The most prominent supra­molecular inter­actions in the crystal packing are carb­oxy­lic acid-H⋯O(carbox­yl) hydrogen bonds that lead to centrosymmetric dimeric aggregates connected by eight-membered {⋯HOC=O}(2) synthons.
