Area of Science:

• Crystal engineering
• Supramolecular chemistry
• Organic chemistry

Background:

• Molecular salts offer tunable properties for materials science.
• Understanding anion conformation is crucial for predicting crystal packing and interactions.
• Hydrogen bonding plays a key role in stabilizing crystal structures.

Purpose of the Study:

• To characterize the crystal structure and conformation of the novel molecular salt 2C(6)H(14)N(+)·C(14)H(8)O(4)S(2) (2-).
• To investigate the role of intermolecular interactions in the crystal lattice.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of bond angles, torsion angles, and intermolecular contacts was performed.

Main Results:

• The molecular salt 2C(6)H(14)N(+)·C(14)H(8)O(4)S(2) (2-) was successfully synthesized and characterized.
• The dianion exhibits a twisted conformation with a C-S-S-C torsion angle of 87.13(2)° and a dihedral angle between rings of 83.4(2)°.
• Intermolecular N-H⋯O hydrogen bonds were identified, linking the cations and anions in the crystal structure.

Conclusions:

• The crystal structure of 2C(6)H(14)N(+)·C(14)H(8)O(4)S(2) (2-) is stabilized by a combination of a unique twisted dianion conformation and N-H⋯O hydrogen bonding.
• This work provides insights into the structural diversity of molecular salts and the factors governing their self-assembly.
