Two molecules of C(15)H(16)N(2)O(4)S were identified in the crystal structure, each stabilized by an intramolecular hydrogen bond. Intermolecular hydrogen bonds further organized these molecules into [101] chains within the crystal lattice.
Area of Science:
- Crystallography
- Chemical physics
Background:
- Understanding molecular interactions is crucial for predicting material properties.
- Hydrogen bonding plays a significant role in stabilizing crystal structures.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(15)H(16)N(2)O(4)S.
- To investigate the types and roles of hydrogen bonding in the molecular assembly.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of hydrogen bonding interactions, including intramolecular and intermolecular types.
Main Results:
- The asymmetric unit contains two molecules of C(15)H(16)N(2)O(4)S.
- Both molecules exhibit stabilization through an intramolecular O-H⋯N hydrogen bond.
- Intermolecular N-H⋯O hydrogen bonds link the molecules into [101] chains.
Conclusions:
- The crystal structure of C(15)H(16)N(2)O(4)S is characterized by specific intramolecular hydrogen bonding.
- These intramolecular interactions, combined with intermolecular hydrogen bonds, dictate the formation of extended [101] chain structures.
