Area of Science:
- Organic Chemistry
- Crystallography
- Molecular Structure Analysis
Background:
- Understanding the precise three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties and reactivity.
- Complex organic compounds often exhibit unique conformational preferences due to steric and electronic interactions between their constituent parts.
Purpose of the Study:
- To elucidate the detailed molecular geometry of the title compound, C(23)H(16)N(2)O.
- To quantify the bond angle at the oxygen bridge and the dihedral angles between the aromatic ring systems.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the atomic coordinates and bond parameters.
- Analysis of the crystallographic data provided precise measurements of bond angles and dihedral angles.
Main Results:
- The bond angle at the oxygen atom connecting the benzene and quinoline ring systems was determined to be 116.0(2)°.
- A dihedral angle of 16.5(2)° was observed between the quinoline ring system and the adjacent benzene ring.
- The dihedral angle between the two benzene rings of the biphenyl moiety was found to be 70.8(2)°.
Conclusions:
