1-Nitro-4-(2-nitroprop-1-enyl)benzene

Abstract

The asymmetric unit of the title compound, C9H8N2O4, contains two crystallographically independent molecules, both of which adopt an E configuration about the C=C bond. In the crystal, the molecules stack into columns along the c axis through π–π interactions, 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.
