N-(4-Methoxybenzylidene)-N'-(2-pyridyl)hydrazine.

Molecules of the title compound (alternative name p-methoxybenzaldehyde 2-pyridylhydrazone), C(13)H(13)N(3)O, adopt an E configuration about the azomethine C=N double bond. Molecules are almost planar, the dihedral angle between the pyridine and methoxyphenyl rings being only 6.19 (12) degrees. Pairwise N-H.N hydrogen bonds [R(2)(2)(8) in graph-set notation] link centrosymmetrically related molecules into discrete pairs.
