This study details the crystal structure of a C14H12O4 compound, revealing dimeric structures formed by C-H…O interactions. The allylic groups exhibit twisting, and the crystal packing forms a zigzag pattern.
Area of Science:
- Crystallography
- Organic Chemistry
- Solid-State Chemistry
Background:
- Understanding molecular interactions and packing in organic solids is crucial for materials science.
- The title compound, C14H12O4, presents an interesting case for structural analysis due to its functional groups.
Purpose of the Study:
- To elucidate the crystal structure and intermolecular interactions of the title compound.
- To analyze the conformation of allylic groups and the packing arrangement in the solid state.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of intermolecular C-H⋯O interactions and dihedral angles was performed.
Main Results:
- The asymmetric unit contains two independent molecules of C14H12O4, forming dimeric entities through C-H⋯O hydrogen bonds.
- Significant twisting of allylic groups out of phenyl planes was observed, with dihedral angles ranging from 7.92(13)° to 25.42(8)°.
- Crystal packing follows a distinct zigzag pattern along the c-axis.
Conclusions:
- The study successfully characterized the crystal structure and supramolecular assembly of the title compound.
- The observed conformational preferences and packing motifs provide insights into the solid-state behavior of this organic molecule.

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...
