Abstract: In the title compound, C12H6F2N2O2, the 2,2-difluoro-1,3-benzodioxole ring system is approximately planar [maximum deviation = 0.012 (2) Å] and its mean plane is twisted with respect to the pyrrole ring, making a dihedral angle of 2.51 (9)°. In the crystal, N-H...N hydrogen bonds link the molecules into chains running along the a axis. [pi]-[pi] stacking is also observed between parallel benzene rings of adjacent molecules, the centroid-centroid distance being 3.7527 (13) Å.
