This study details the crystal structure of a chloro-substituted organic compound, C(14)H(12)ClNO. Molecular analysis reveals a specific dihedral angle between aromatic rings and hydrogen bonding that forms crystal chains.
Area of Science:
- Crystallography
- Organic Chemistry
- Materials Science
Background:
- Understanding the three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties.
- Crystal engineering utilizes intermolecular forces to design materials with desired characteristics.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(14)H(12)ClNO.
- To investigate the intermolecular interactions governing the solid-state packing of this molecule.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, bond angles, and dihedral angles provided detailed structural insights.
Main Results:
- The crystal structure of C(14)H(12)ClNO was successfully determined.
- A dihedral angle of 59.25(5)° was measured between the aromatic rings.
- Disordered methyl group observed over two equally occupied positions.
- N-H⋯O hydrogen bonds were identified, forming infinite C(4) chains along the a axis.
Conclusions:
- The crystal packing is primarily dictated by N-H⋯O hydrogen bonding, leading to the formation of extended chain structures.
- The observed structural features, including ring orientation and methyl group disorder, provide fundamental data for understanding structure-property relationships in related compounds.

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...
