(E)-Methyl 1,3-thia­zol-2-yl ketone 2,4-dinitro­phenyl­hydrazone

Crystals of the title compound, C(11)H(9)N(5)O(4)S, were obtained from a condensation reaction of 2,4-dinitro­phenyl­hydrazine and methyl 1,3-thia­zol-2-yl ketone. Excluding two methyl H atoms, the mol­ecule displays a planar structure, the dihedral angle between the terminal thia­zole and benzene rings being 1.82 (8)°. The imino group links with adjacent nitro and thia­zole groups by intra­molecular bifurcated hydrogen bonding. The centroid–centroid separation of 3.7273 (11) Å between nearly parallel benzene and thia­zole rings of adjacent mol­ecules indicates the existence of π–π stacking in the crystal structure. Weak inter­molecular C—H⋯O hydrogen bonding is also observed.
