title: (E)-1-(2,4-Dinitro-phen-yl)-2-[1-(4-fluoro-phen-yl)ethyl-idene]hydrazine.
abstract: The title compound, C(14)H(11)FN(4)O(4), crystallizes with two essentially planar mol-ecules in the asymmetric unit; the dihedral angles between the benzene rings are 1.57 (15) and 6.17 (15)°. In each mol-ecule, an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯F inter-actions into sheets lying parallel to (120). O⋯C [2.980 (4) Å] and O⋯N [2.892 (3) Å] short contacts also occur.
