Area of Science:

• Crystallography
• Chemical Physics
• Materials Science

Background:

• Understanding molecular interactions is crucial for designing new materials.
• Thio-urea compounds exhibit diverse structural properties and applications.
• Hydrogen bonding plays a significant role in molecular self-assembly.

Purpose of the Study:

• To elucidate the crystal structure and intermolecular interactions of a specific thio-urea compound.
• To investigate the factors stabilizing the molecular conformation.
• To characterize the self-assembly behavior leading to one-dimensional chains.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of intra-molecular and inter-molecular interactions, including hydrogen bonds and C-H⋯S contacts.
• Geometric analysis of the thio-urea group to determine cis-trans configuration.

Main Results:

• The title compound, C(12)H(14)N(2)O(3)S, was found to adopt a cis-trans geometry for the thio-urea moiety.
• Intra-molecular hydrogen bonds (between carbonyl O and thio-amide H) and a C-H⋯S interaction stabilize the molecule.
• Two inter-molecular hydrogen bonds (C-H⋯O and N-H⋯O) link molecules into a one-dimensional chain along the c axis.

Conclusions:

• The crystal structure reveals a unique stabilization mechanism involving both intra- and inter-molecular forces.
• The observed hydrogen bonding network dictates the formation of 1D chains, offering insights into crystal engineering.
• This study provides a detailed structural characterization of a novel thio-urea derivative.
