Abstract:
The structure of the title compound, C18H15ClN4, was determined at low temperature (100 K). In the crystal, the mol-ecules are connected through C-H⋯N and C-H⋯Cl inter-molecular hydrogen bonds generating a network that extend along the [010] direction. In addition, C-H⋯π and π-π stacking inter-actions as well as inter-molecular contacts contribute to the cohesion of the structure. Hirshfeld surface analysis indicates that the contributions to the surface for the H⋯H, H⋯N/ N⋯H, H⋯C/C⋯H, H⋯Cl/Cl⋯H and C⋯C contacts are 30.2, 19.9, 28.6, 12.2 and 3.7%, respectively.

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...
