This study details the crystal structure of C(14)H(12)ClNO, revealing two independent molecules with specific dihedral angles. Intermolecular hydrogen bonds stabilize the crystal lattice, forming chains along the c axis.
Area of Science:
- Crystallography
- Solid-state chemistry
- Molecular structure
Background:
- Understanding molecular arrangements in crystals is crucial for materials science.
- The compound C(14)H(12)ClNO is a novel chemical entity whose solid-state properties are yet to be fully characterized.
- Previous studies may not have elucidated the specific intermolecular interactions governing its crystal packing.
Purpose of the Study:
- To determine the precise three-dimensional arrangement of atoms in the crystal structure of C(14)H(12)ClNO.
- To investigate the dihedral angles between aromatic rings within the molecule.
- To identify and characterize the intermolecular forces responsible for crystal stabilization.
Main Methods:
- Single-crystal X-ray diffraction was employed to collect diffraction data.
- The crystal structure was solved and refined using standard crystallographic software.
- Analysis of bond lengths, bond angles, and intermolecular interactions was performed.
Main Results:
- The asymmetric unit contains two independent molecules of C(14)H(12)ClNO.
- The dihedral angles between the two aromatic rings were measured as 51.76(6)° and 51.48(7)°.
- Intermolecular N-H⋯O hydrogen bonds were identified, linking molecules into chains along the c axis.
Conclusions:
- The crystal structure of C(14)H(12)ClNO is characterized by the presence of two independent conformers.
- The observed dihedral angles provide insights into the conformational flexibility of the molecule in the solid state.
- The crystal packing is significantly influenced by N-H⋯O hydrogen bonding, leading to a chain-like supramolecular architecture.

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...
