(E)-1-(2,4-Dinitro-phen-yl)-2-pentyl-idenehydrazine.

ABSTRACT: 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.
