Ethyl 4-chloro-3,5-dinitrobenzoate
Abstract
In the title compound, C9H7ClN2O6, the nitro groups and the ester group make dihedral angles of 44.0 (1), 89.6 (1) and 164.1 (1)°, respectively, with the benzene ring. In the crystal, molecules are linked through weak C—H...O hydrogen-bonding interactions. Molecules are stacked via π–π interactions about inversion centers, with a centroid–centroid distance of 3.671 (2) Å.
