title: 1-Nitro-4-(2-nitro-prop-1-en-yl)benzene.
abstract: The asymmetric unit of the title compound, C(9)H(8)N(2)O(4), contains two crystallographically independent mol-ecules, both of which adopt an E configuration about the C=C bond. In the crystal, the mol-ecules stack into columns along the c axis through π-π inter-actions, with centroid-centroid distances of 3.695 (3) and 3.804 (3) Å. The columns are further connected into a three-dimensional network by C-H⋯O hydrogen bonds.
