- The formation of hydrogen bonds plays a significant role in the self-assembly and stability of crystalline structures.
- Quinoline and acetamide moieties are common structural motifs in pharmaceuticals and materials science.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(18)H(16)N(2)O(2)·H(2)O.
- To analyze the dihedral angle between the quinoline and benzene ring systems.
- To investigate the intermolecular interactions, specifically hydrogen bonding, within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- The crystal structure was analyzed to identify hydrogen bond donors and acceptors.
- Geometric parameters, including dihedral angles and bond lengths/angles, were precisely measured.
Main Results:
- The crystal structure of C(18)H(16)N(2)O(2)·H(2)O was successfully determined.
- A significant dihedral angle of 87.19(8)° was observed between the quinoline and benzene ring systems.

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
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...

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
