title: 1-(But-2-enyl-idene)-2-(2-nitro-phen-yl)hydrazine.
abstract: The mol-ecule of the title Schiff base compound, C(10)H(11)N(3)O(2), adopts an E geometry with respect to the C=N double bond. The mol-ecule is roughly planar, with the largest deviation from the mean plane being 0.111 (2) Å, The enyl-idene-hydrazine group is, however, slightly twisted with respect to the phenyl ring, making a dihedral angle of 6.5 (3)°. An intra-molecular N-H⋯O hydrogen bond may be responsible for the planar conformation. An inter-molecular N-H⋯O hydrogen bond links two mol-ecules around an inversion center, building a pseudo dimer.
