In-situ cryocrystallization of 1,2-dimethyl-3-nitro­benzene and 2,4-dimethyl-1-nitro­benzene

The crystal structures of 1,2-dimethyl-3-nitro­benzene and 2,4-dimethyl-1-nitro­benzene, which are liquids at room temperature, have been obtained through in-situ cryocrystallization. Weak C—H...O and π–π inter­actions have been identified in both compounds.
