• Supramolecular Chemistry

Background:

• Understanding molecular conformation and crystal packing is crucial in materials science and drug design.
• Organic compounds with nitrogen and aromatic rings exhibit diverse structural properties and intermolecular interactions.

Purpose of the Study:

• To elucidate the precise molecular structure and conformation of the title compound, C(18)H(24)N(2).
• To investigate the intermolecular interactions governing the crystal packing of this compound.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of torsion angles and dihedral angles provided insights into the molecular conformation.
• Intermolecular interactions, including C-H⋯N and C-H⋯π contacts, were identified and analyzed.

Main Results:

• The molecular unit adopts a trans conformation around the central C-C bond with a torsion angle of 179.2°.
• The two aromatic rings are nearly coplanar, with a dihedral angle of 0.70°.
• Crystal packing is characterized by cooperative weak C-H⋯N and C-H⋯π interactions, optimizing space filling.

Conclusions:
