This study details the molecular structure of a novel organic compound, C(28)H(24)N(2)O(4). The research highlights specific dihedral angles between its aromatic rings and identifies stabilizing hydrogen bonds within its crystal structure.
Area of Science:
- Organic Chemistry
- Crystallography
- Molecular Structure
Background:
- Understanding the three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties and reactivity.
- Biphenyl units are common structural motifs in various functional organic materials.
Purpose of the Study:
- To elucidate the precise molecular geometry of the title compound, C(28)H(24)N(2)O(4).
- To investigate the stabilizing interactions, including hydrogen bonding, within the molecule and its crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the three-dimensional structure.
- Analysis of bond lengths, bond angles, and dihedral angles provided detailed structural information.
Main Results:
- The dihedral angle between the biphenyl unit's rings was determined to be 75.34(9)°.
- Outer aromatic rings exhibited significant dihedral angles of 66.96(1)° and 85.69(8)° relative to their attached rings.
- Intramolecular C-H⋯O and N-H⋯O hydrogen bonds were identified, stabilizing the molecular conformation.
- Intermolecular N-H⋯O interactions were observed in the crystal structure.
Conclusions:
- The study provides a detailed structural characterization of C(28)H(24)N(2)O(4), revealing a non-planar biphenyl core.
- Hydrogen bonding plays a significant role in both intramolecular stabilization and intermolecular packing in the solid state.

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
IUPAC Nomenclature of Carboxylic Acids
For acyclic saturated monocarboxylic acids, the longest hydrocarbon chain containing the –COOH carbon is identified as the parent chain. Then, the last -e of the parent hydrocarbon name is replaced with a suffix -oic acid.

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...
