Key indicators: single-crystal X-ray study; T = 153 K; mean (C-C) = 0.002 Å; R factor = 0.047; wR factor = 0.151; data-to-parameter ratio = 15.7. In the title molecule, C 21 H 16 N 2 O, the anthracene ring system is slightly twisted with a dihedral angle of 1.22 (1) between the two outermost rings. The anthracene mean plane and pyridine ring make a dihedral angle of 72.6 (1) . The Á Á Á interactions [3.551 (2) Å ] between the anthracene fragments form stacks of molecules parallel to the b axis.
