2,4-Dinitrophenylhydrazine, redetermined at 120K: A three-dimensional framework built from N - H⋯O, N - H⋯- H(arene) ⋯πand C - HO hydrog⋯en bonds

Abstract

In the title compound, C6H6N4O 4, the bond distances indicate significant bond fixation, consistent with charge-separated polar forms. The molecules are almost planar and there is an intramolecular N - H⋯O hydrogen bond. The molecules are linked into a complex three-dimensional framework structure by a combination of N - H⋯O, N - H⋯(O)2, N - H⋯π(arene) and C - H⋯O hydrogen bonds. © 2006 International Union of Crystallography.
