This study details the crystal structure of C(13)H(11)N(3)O(2), revealing two distinct molecular conformations. Analysis highlights intramolecular hydrogen bonds and intermolecular N-H⋯O interactions forming specific ring structures in the crystal lattice.
Area of Science:
- Crystallography
- Molecular Chemistry
- Organic Chemistry
Background:
- Understanding molecular conformation is crucial for predicting chemical properties.
- Crystal packing influences intermolecular interactions and solid-state behavior.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(13)H(11)N(3)O(2).
- To analyze the conformational differences and intermolecular interactions within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, angles, and non-covalent interactions was performed.
Main Results:
- The asymmetric unit contains two molecules with slightly different dihedral angles between aromatic rings (13.01° and 14.05°).
- Short intramolecular C-H⋯O contacts forming S(6) rings were observed in both molecules.
- Inversion dimers, linked by N-H⋯O hydrogen bonds forming R(2)(2)(16) rings, characterize the crystal structure.
Conclusions:
- The crystal structure of C(13)H(11)N(3)O(2) exhibits conformational variability and specific hydrogen bonding patterns.
- Intramolecular and intermolecular interactions dictate the observed crystal packing and supramolecular architecture.
