Area of Science:

• Crystallography and Molecular Structure
• Supramolecular Chemistry

Background:

• Understanding the factors that influence molecular conformation is crucial in chemistry.
• Hydrogen bonding plays a significant role in stabilizing molecular structures.

Purpose of the Study:

• To characterize the molecular salt C(21)H(25)N(4)S(3)(+)·ClO(4)(-).
• To investigate the role of intramolecular hydrogen bonding in cation conformation.

Main Methods:

• Single-crystal X-ray diffraction analysis was performed.
• Analysis of torsion angles to determine molecular geometry.

Main Results:

• The molecular salt C(21)H(25)N(4)S(3)(+)·ClO(4)(-) was successfully synthesized and characterized.
• An intramolecular N-H⋯N hydrogen bond was identified, stabilizing the cation's conformation.
• Key N-C-C-S torsion angles were determined to be 91.7(2)°, 100.9(2)°, and 167.02(14)°.

Conclusions:

• Intramolecular hydrogen bonding is a key factor in the conformational stability of this molecular salt cation.
• The determined torsion angles provide precise geometric data for this specific molecular structure.
