3-(4-MethÂoxyÂphenÂyl)pyrido[2,3-b]pyrazine
In the title molÂecule, C14H11N3O, the benzene ring is twisted by 14.0 (2)° from the plane through the fused ring system. In the crystal, π–π interÂactions [centroid–centroid distances = 3.609 (1), 3.639 (1) and 3.735 (1) Å] form stacks of molÂecules propagating along the b axis. The crystal packing is further stabilized by weak interÂmolecular C—H⋯O and C—H⋯N hydrogen bonds
