3-(4-Methoxyphenyl)pyrido[2,3-b]pyrazine

Abstract

In the title molecule, C14H11N3O, the benzene ring is twisted by 14.0 (2)° from the plane through the fused ring system. In the crystal, π–π interactions [centroid–centroid distances = 3.609 (1), 3.639 (1) and 3.735 (1) Å] form stacks of molecules propagating along the b axis. The crystal packing is further stabilized by weak intermolecular C—H...O and C—H...N hydrogen bonds.
