Abstract:
The asymmetric unit of the title compound, C14H10N2O2, contains two independent mol-ecules. In each mol-ecule, the benzodioxole ring system displays an envelope conformation, with the methyl-ene C atom located at the flap deviating by 0.081 (2) and 0.230 (2) Å from the mean plane formed by the other atoms. The dihedral angles between the benzo-imidazole ring system (all atoms) and the benzodioxole benzene ring are 15.35 (6) and 10.99 (7)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into chains running along the [101].
