title: 2-Nitro-N'-[1-(pyridin-2-yl)ethyl-idene]benzohydrazide.
abstract: In the title compound, C(14)H(12)N(4)O(3), the dihedral angle between the benzene ring and the pyridine ring is 60.9 (2)°. The major twist in the mol-ecule occurs about the (NH)-(CO)-C(ar)-C(ar) (ar = aromatic) bond, the relevant torsion angle being 63.97 (12)°. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
