Abstract:
In the title mol-ecule, C14H10ClNO3, the amide C=O bond is anti to the o-carb-oxy substituent in the adjacent benzene ring, a conformation that facilitates the formation of an intra-molecular amide-N-H⋯O(carbon-yl) hydrogen bond that closes an S(6) loop. The central amide segment is twisted away from the carb-oxy- and chloro-substituted benzene rings by 13.93 (17) and 15.26 (15)°, respectively. The most prominent supra-molecular inter-actions in the crystal packing are carb-oxy-lic acid-H⋯O(carbox-yl) hydrogen bonds that lead to centrosymmetric dimeric aggregates connected by eight-membered {⋯HOC=O}2 synthons.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
