Abstract The title compound (IV) was isolated as a by-product during the course of purification of 4-nitroimidazol-5-(N′-methyl)hydrazide (II) by silica gel flash chromatography, employing chloroform-acetone (4:1) as the eluting solvent. The crystals are monoclinic, space groupP21/c,a=7.425(1),b=13.615(2),c=10.359(2) Å,β=97.66(1)°,d caled=1.44 g cm−3,μ (MoKα)=1.06 mm−1,T=298 K. The number of unique reflections=2401, reflections withI≥3 σ(I)=1773;R=0.051,R w =0.061. The bond distances inIV are: N-N, 1.419(3); N-C(=0), 1.359(3); N(H)-C(CH3), 1.457(3); N(C)-C(CH3), 1.501(3); N=C, 1.316(3); C=C, 1.368(3), N-C(=N), 1.353(3); N-C(=C), 1.367(2) Å.
