Background:

• Understanding the molecular structure and intermolecular forces of organic compounds is crucial for predicting their physical and chemical properties.
• C(14)H(16)N(2)S(2) is a novel compound with potential applications in materials science.

Purpose of the Study:

• To elucidate the complete molecular structure of C(14)H(16)N(2)S(2) using X-ray crystallography.
• To analyze the conformation, bond characteristics, and intermolecular interactions within the crystal lattice.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the three-dimensional structure.
• Analysis of bond lengths, torsion angles, and intermolecular contacts (C-H⋯N, C-H⋯π, S⋯S) was performed.

Main Results:

• The molecule C(14)H(16)N(2)S(2) is centrosymmetric, generated by a crystallographic inversion center.
• The thiophene ring and imine group exhibit near-coplanarity (torsion angle 6.5°).
• The imine bond length is 1.281 Å, with an E conformation. Significant S⋯S interactions (3.3932 Å) were observed.

Conclusions:

• The crystal structure of C(14)H(16)N(2)S(2) is stabilized by a combination of hydrogen bonds, C-H⋯π interactions, and S⋯S contacts.
• The determined structural features provide fundamental insights into the solid-state behavior of this compound.
• Further research can explore the implications of these structural characteristics for material properties.
