Y. Kawai, M. Hayashi and N. Tokitoh

Abstract: The molecule of the title compound, C₉H₉ClN₄O₄, is nearly planer except for the ortho-nitro group, with the non-H atoms exhibiting an average deviation of 0.099 Å from the mean plane. The ortho-nitro group is nearly perpendicular to the phenyl group, with a dihedral angle of 88.46 (3)°. The N-N and N=C bond lengths of the isopropylidene-hydrazine moiety are 1.3928 (14) and 1.2865 (15) Å, respectively.
