• Pyridine-containing compounds are prevalent in pharmaceuticals and functional materials, necessitating detailed structural analysis.

Purpose of the Study:

• To elucidate the crystal structure of the title compound C(12)H(12)N(2).
• To identify and analyze intermolecular interactions governing the compound's solid-state arrangement.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the three-dimensional structure.
• Analysis of crystallographic data to identify symmetry elements and intermolecular contacts.

Main Results:

• The asymmetric unit contains two half-molecules related by an inversion center.
• Pyridine rings are oriented at a dihedral angle of 69.62(4)°.
• A π-π contact between pyridine rings (3.895(3) Å) and a weak C-H⋯π interaction were identified.

Conclusions:

• The crystal structure of C(12)H(12)N(2) is characterized by specific molecular arrangements and intermolecular forces.
• The observed π-π and C-H⋯π interactions likely play a significant role in stabilizing the crystal lattice.
