Abstract
The structures of m-dinitrobenzene and p-dinitrobenzene have been refined by three-dimensional (Fo—Fc) syntheses. The results indicate that both nitro groups in each molecule are twisted 11° out of the aromatic plane, about the C—N bonds, in contrast to nitrobenzene, where the whole molecule is completely planar. These molecular configurations are shown to be in accord with those which might be expected from intramolecular steric effects. The dimensions of the three molecules have also been compared.Keywords
