Abstract:
Mutual carbox-yl-carboxyl O-H⋯O hydrogen bonds link the mol-ecules of the title compound, C7H5BrO3, into centrosymmetric dimers which display a central R 2 (2)(8) ring motif. In addition, there is an intra-molecular hydrox-yl-carboxyl O-H⋯O inter-action present. A comparison with the crystal structures of 59 other substituted derivatives of salicylic acid shows that both the centrosymmetric carbox-yl-carboxyl O-H⋯O dimer and the stacking mode of mol-ecules along the short a axis observed in the title structure are frequent packing motifs in this set.

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...
