Abstract
The title compound, C14H10N2O, crystallizes in the monoclinic space group P21/c with four molecules in the unit cell. All 17 non-H atoms of one molecule lie essentially in one plane. In the unit cell, two pairs of molecules are exactly coplanar, while the angle between these two orientations is close to perfectly perpendicular at 87.64 (6)°. In the crystal, molecules adopt a 50:50 crisscross arrangement, which is held together by two nonclassical and two classical intermolecular hydrogen bonds. The hydrogen-bonding network together with off-centre π–π stacking interactions between the pyridine and outermost benzene rings, stack the molecules along the b-axis direction.
