title: [1-Phenyl-2-(4-pyrid-yl)ethyl-idene]hydrazine.
abstract: The title compound, C(13)H(13)N(3), is non-planar, with the pyridine and phenyl rings inclined at an angle of 80.7 (3)°. The central ethyl-idenehydrazine atoms lie in a plane [mean deviation = 0.013 (1) Å], which forms dihedral angles of 88.5 (1) and 9.4 (1)° with the pyridine and phenyl rings, respectively. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯N hydrogen bonds into infinite chains propagating along the b axis.
