This study details the crystal structure of a molecule with formula C(19)H(22)N(4)O(2)S. It reveals specific dihedral angles and intermolecular interactions that organize molecules into dimers and sheets.
Area of Science:
- Crystallography
- Molecular Structure
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 of C(19)H(22)N(4)O(2)S.
- To analyze intermolecular forces governing crystal packing.
Main Methods:
- Single-crystal X-ray diffraction analysis.
- Analysis of hydrogen bonding and other non-covalent interactions.
Main Results:
- The molecule C(19)H(22)N(4)O(2)S exhibits a dihedral angle of 9.16° between its benzene rings.
- Weak intermolecular C-H⋯S hydrogen bonds form centrosymmetric dimers.
- Further linkage via C-H⋯O interactions creates sheets parallel to the (012) plane.
Conclusions:
- The crystal structure is stabilized by a combination of C-H⋯S and C-H⋯O interactions.
- These interactions dictate the formation of dimers and extended sheet networks.
