This study details a novel diaza-borinane compound with a near-planar structure. Molecular analysis reveals specific distortions and intermolecular interactions like pi-pi stacking in its crystalline form.
Area of Science:
- Organic Chemistry
- Crystallography
- Supramolecular Chemistry
Background:
- Diaza-borinanes are heterocyclic compounds containing nitrogen and boron.
- Substitution patterns significantly influence the structural and electronic properties of these heterocycles.
Purpose of the Study:
- To synthesize and characterize a novel diaza-borinane derivative.
- To investigate the structural features and intermolecular interactions of the title compound.
Main Methods:
- Single-crystal X-ray diffraction was used to determine the molecular structure.
- Analysis of bond lengths, bond angles, torsion angles, and intermolecular interactions (π-π stacking, C-H⋯π interactions).
Main Results:
- The title compound, C(16)H(13)BN(2), exhibits a slightly distorted planar geometry.
- A dihedral angle of 9.0(5)° was observed between the naphthalene and benzene ring systems.
- Molecules form columns in the crystal lattice via π-π interactions between naphthalene centroids (3.92(3) Å) and are further linked by C-H⋯π interactions.
Conclusions:
- The study provides detailed structural insights into a substituted diaza-borinane.
- The observed intermolecular interactions highlight potential for crystal engineering and material design.
