This study details the crystal structure of a novel organic compound, C(12)H(10)N(2)OS. The phenyl and thiophene rings exhibit a specific dihedral angle, with hydrogen bonds forming characteristic inversion dimers in the crystal lattice.
Area of Science:
- Crystallography
- Organic Chemistry
- Supramolecular Chemistry
Background:
- Understanding the three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties.
- Intermolecular interactions, such as hydrogen bonding, play a significant role in the self-assembly of molecules in the solid state.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(12)H(10)N(2)OS.
- To analyze the dihedral angle between the phenyl and thiophene rings.
- To investigate the hydrogen bonding patterns and their role in crystal packing.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of the crystal structure included bond lengths, bond angles, and dihedral angles.
- Identification and analysis of intermolecular interactions, specifically N-H⋯O hydrogen bonds.
Main Results:
- The crystal structure of C(12)H(10)N(2)OS was successfully determined.
- A dihedral angle of 10.2(3)° was measured between the phenyl and thiophene rings.
- Inversion dimers, stabilized by pairs of N-H⋯O hydrogen bonds, were observed, forming R(2)(2)(8) loops.
Conclusions:
- The study provides detailed structural information for the compound C(12)H(10)N(2)OS.
- The observed dihedral angle suggests a near-planar arrangement between the aromatic rings.
- The hydrogen bonding network dictates the formation of specific supramolecular architectures in the solid state.

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...
