Abstract
In the title compound, C14H12N2, the N⋯N distance is 2.719 (1) Å. The N—C—C—N torsion angle [0.9 (1)°] is close to the ideal value of 0° as expected. Bond lengths and angles are consistent with those observed for [1,10]phenanthroline and coordinated 5,6 dimethyl[1,10]phenanthroline. In the crystal, C—H⋯N hydrogen bonds link the molecules into C(4) chains running parallel to the b axis. Weak π–π interactions between benzene and pyridine rings [centroid–centroid distance = 3.5337 (7) Å] and between benzene rings [centroid–centroid distances = 3.6627 (7) and 3.8391 (7)Å] also occur.

Key indicators: single-crystal X-ray study; T = 100 K; mean (C–C) = 0.002 A; R factor = 0.035; wR factor = 0.100; data-to-parameter ratio = 10.8. The N—C—C—N torsion angle [0.9 (1)] is close to the ideal value of 0 as expected.
