The crystal structure of C(14)H(10)N(2)O(4) reveals a dihedral angle of 53.66° between benzene rings. Molecules form chains via intermolecular C-H⋯O hydrogen bonds.
Area of Science:
- Crystal chemistry
- Supramolecular chemistry
Background:
- Understanding molecular interactions is key in crystal engineering.
- Dihedral angles influence molecular packing and properties.
Purpose of the Study:
- To elucidate the crystal structure and intermolecular interactions of the title compound C(14)H(10)N(2)O(4).
Main Methods:
- Single-crystal X-ray diffraction analysis.
- Analysis of intermolecular C-H⋯O hydrogen bonding.
Main Results:
- The dihedral angle between the benzene rings in C(14)H(10)N(2)O(4) was determined to be 53.66(5)°.
- Molecules are organized into chains along the [01] direction.
- Intermolecular C-H⋯O hydrogen bonds facilitate chain formation.
Conclusions:
- The crystal packing is governed by specific dihedral angles and hydrogen bonding.
- The identified hydrogen bonding motif provides insights into the self-assembly of the molecule.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
