Abstract:
In the title solvated mol-ecular salt, C18H22BrN2O3 +·Cl-·CH3CN, the imidazole ring is in envelope conformation and the pyridine and phenyl rings are oriented at a dihedral angle of 72.52 (5)°. In the crystal, O-H⋯Cl and N-H⋯Cl hydrogen bonds link the cations and anions into centrosymmetric tetra-mers enclosing R 2 4(12) loops. Short Br⋯Cl [3.2313 (4) Å] and O⋯Cl [3.0490 (10) Å] contacts are observed. A Hirshfeld surface analysis of the structure indicates that the most important contributions for the crystal packing are from H⋯H (52.4%), H⋯C/C⋯H (12.1%), H⋯Br/Br⋯H (11.0%) and H⋯Cl/Cl⋯H (10.2%) inter-actions.

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...

Preparation of Acid Anhydrides
The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...
