چکیده
The title compound, C(11)H(14)N(4)O(4), is essentially planar with an r.m.s. deviation for the 19 non-H atoms of 0.152 Å. The conformation about the C=N bond is E, and the mol-ecule has a U-shape as the butyl group folds over towards the aromatic system. An intra-molecular C-H⋯N inter-action occurs. The crystal packing is dominated by N-H⋯O hydrogen bonding and C-H⋯O contacts, leading to twisted zigzag supra-molecular chains along the c direction. The crystal packing brings two nitro O atoms into an unusually close proximity of 2.686 (4) Å. While the nature of this inter-action is not obvious, there are several precendents for such short nitro-nitro O⋯O contacts of less than 2.70 Å in the crystallographic literature.

The title compound, C(14)H(11)N(5)O(6), was obtained from the condensation reaction of 2,4-dinitro-phenyl-hydrazine and 2-nitro-acetophenone. The mol-ecule displays an E conformation about the C=N double bond and an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. The dihedral angle between the benzene rings is 7.84 (6)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen ...
