title: (E)-Methyl 1,3-thia-zol-2-yl ketone 2,4-dinitro-phenyl-hydrazone.
abstract: Crystals of the title compound, C(11)H(9)N(5)O(4)S, were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and methyl 1,3-thia-zol-2-yl ketone. Excluding two methyl H atoms, the mol-ecule displays a planar structure, the dihedral angle between the terminal thia-zole and benzene rings being 1.82 (8)°. The imino group links with adjacent nitro and thia-zole groups by intra-molecular bifurcated hydrogen bonding. The centroid-centroid separation of 3.7273 (11) Å between nearly parallel benzene and thia-zole rings of adjacent mol-ecules indicates the existence of π-π stacking in the crystal structure. Weak inter-molecular C-H⋯O hydrogen bonding is also observed.
