This study details the molecular structure of a novel compound, C(19)H(18)O(5). Analysis reveals specific dihedral angles between its functional groups and benzene rings, with no significant intermolecular interactions in its crystal packing.
Area of Science:
- Crystallography
- Organic Chemistry
- Molecular Structure Analysis
Background:
- Understanding the three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties and reactivity.
- Eugenol and acetyl-salicylic acid are compounds with significant biological and pharmaceutical relevance.
Purpose of the Study:
- To elucidate the precise molecular geometry of the title compound, C(19)H(18)O(5).
- To analyze the spatial relationships between the ester group, acetyl-salicylic acid moiety, and eugenol moiety.
- To investigate intermolecular interactions within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular structure.
- Dihedral angles were calculated to quantify the twist between different molecular fragments.
- Crystal packing was analyzed for short intermolecular contacts.
Main Results:
- The ester group exhibits significant twists relative to the acetyl-salicylic acid ring (22.48°) and the eugenol ring (81.07°).
- A dihedral angle of 60.72° was observed between the two primary benzene rings.
- No short intermolecular contacts were detected in the crystal packing, suggesting weak inter-molecular forces.
Conclusions:
- The title compound possesses a distinct three-dimensional structure characterized by specific torsional angles.
- The observed molecular conformation and lack of significant intermolecular contacts provide insights into the compound's solid-state behavior.
- This structural data serves as a foundation for further studies on the compound's chemical and physical properties.
