This study details the crystal structure of a novel organic compound, C(13)H(12)N(2)O(2)S. The research highlights the specific dihedral angle between its aromatic rings and the formation of hydrogen bonds in its crystalline state.
Area of Science:
- Crystallography
- Organic Chemistry
- Molecular Structure
Background:
- Understanding molecular interactions is crucial in organic chemistry.
- Crystal structure analysis reveals detailed spatial arrangements of atoms.
- Hydrogen bonding plays a significant role in molecular self-assembly.
Purpose of the Study:
- To determine the precise crystal structure of the compound C(13)H(12)N(2)O(2)S.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
