This study analyzes the crystal structure of C(16)H(12)N(2)O, revealing specific dihedral angles between phenyl rings. Molecules form dimers through hydrogen bonds, influencing crystal packing via π-π stacking and C-H⋯π interactions.
Area of Science:
- Crystallography
- Organic Chemistry
- Supramolecular Chemistry
Background:
- Understanding molecular interactions is crucial for predicting material properties.
- Crystal structure analysis provides insights into intermolecular forces.
- The title compound, C(16)H(12)N(2)O, presents an interesting case for structural investigation.
Purpose of the Study:
- To determine the crystal structure of C(16)H(12)N(2)O.
- To investigate the dihedral angles between phenyl rings within the molecule.
- To elucidate the intermolecular interactions governing crystal packing.
Main Methods:
- Single-crystal X-ray diffraction was employed to analyze the crystal structure.
- Dihedral angles between phenyl rings were measured.
- Intermolecular interactions, including hydrogen bonds and π-π stacking, were identified.
Main Results:
- Four molecules of C(16)H(12)N(2)O were found in the asymmetric unit.
- Dihedral angles between phenyl rings ranged from 22.2(2)° to 41.9(2)°.
- Intermolecular C-H⋯O hydrogen bonds formed dimers, creating R(2)(2)(10) and R(2)(1)(7) ring motifs. Aromatic π-π stacking and C-H⋯π interactions were also observed.
Conclusions:
- The crystal structure of C(16)H(12)N(2)O is characterized by specific phenyl ring orientations.
- Intermolecular hydrogen bonding and π-π stacking significantly influence the crystal packing.
- These findings contribute to the understanding of supramolecular assembly in organic crystals.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
