title: (E)-1-(2,4-Dinitro-phen-yl)-2-[1-(thio-phen-2-yl)ethyl-idene]hydrazine.
abstract: The mol-ecule of the title compound, C(12)H(10)N(4)O(4)S, is slightly twisted, with a dihedral angle of 8.23 (9)° between the benzene and thio-phene rings. One nitro group is co-planar [O-N-C-C torsion angles = -0.5 (3) and -1.9 (3)°] whereas the other is slightly twisted with respect to the benzene ring [O-N-C-C torsion angles = -5.1 (3) and -5.7 (3)°]. In the crystal, the mol-ecules are linked by weak C-H⋯O inter-actions into screw chains along the b axis. The mol-ecular conformation is consolidated by an intra-molecular N-H⋯O hydrogen bond.
