(E)-2-Furyl methyl ketone 2,4-dinitro-phenyl-hydrazone.

Crystals of the title compound, C(12)H(10)N(4)O(5), were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and 2-furyl methyl ketone. The mol-ecule displays a nearly planar structure, and the furan ring is slightly twisted by a dihedral angle of 12.62†(6)° with respect to the phenyl-hydrazone plane. The face-to-face separation of 3.287†(7)†à between parallel benzene rings of adjacent mol-ecules indicates the existence of π-π stacking between dinitro-phenyl rings in the crystal structure.
