title: 4-(2,2-Difluoro-1,3-benzodioxol-4-yl)-1H-pyrrole-3-carbonitrile.
abstract: In the title compound, C(12)H(6)F(2)N(2)O(2), 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 mol-ecules into chains running along the a axis. π-π stacking is also observed between parallel benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.7527 (13) Å.
