Summary
The crystal structure of a novel organic compound reveals a twisted imidazolidine ring. Molecules are connected through slipped pi-pi interactions between benzene rings in the solid state.
Area of Science:
- Organic Chemistry
- Crystallography
- Supramolecular Chemistry
Background:
- Understanding molecular conformation and intermolecular interactions is crucial in crystal engineering.
- The study of organic compounds with nitrogen and sulfur heteroatoms provides insights into novel material properties.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(17)H(18)N(2)S.
- To investigate the conformational preferences of the imidazolidine ring and the intermolecular interactions present in the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of the crystal packing revealed the nature and geometry of intermolecular interactions.
Main Results:
- The imidazolidine ring in the title compound adopts a twisted conformation.
- Slipped π-π interactions were identified between the benzene rings of adjacent molecules, with a centroid-to-centroid distance of 3.903(2) Å.
Conclusions:
- The crystal structure is stabilized by slipped π-π stacking interactions.
- The conformational flexibility of the imidazolidine ring influences the overall crystal packing.
