N-(2-Chloro-phen-yl)-2-methyl-benzamide
The crystal structure of N2CP2MBA reveals specific molecular conformations and dihedral angles. Molecules pack into chains via N-H⋯O hydrogen bonds, offering insights into crystal engineering.
Area of Science:
- Organic Chemistry
- Crystallography
- Supramolecular Chemistry
Background:
- Understanding molecular conformation and intermolecular interactions is crucial in crystal engineering.
- Previous studies on related benzamide derivatives provide a basis for comparison.
Purpose of the Study:
- To elucidate the crystal structure and molecular conformation of the title compound, C(14)H(12)ClNO (N2CP2MBA).
- To investigate the intermolecular interactions governing crystal packing.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the three-dimensional structure.
- Conformational analysis of bond orientations and dihedral angles was performed.
Main Results:
- The N-H and C=O bonds exhibit a trans conformation.
- The amide group forms similar dihedral angles with the aniline and benzoyl rings (approx. 41-42°).
- The dihedral angle between the benzoyl and aniline rings is small (approx. 7.4°), indicating near planarity.
- N-H⋯O hydrogen bonds facilitate the formation of molecular chains in the crystal lattice.
Conclusions:
- The study provides detailed structural insights into N2CP2MBA, highlighting specific conformational preferences.
- The observed hydrogen bonding pattern explains the observed crystal packing, relevant for designing organic materials.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
