Abstract

The asymmetric unit of the title compound, C(13)H(12)N(2)O(2), obtained in a search for analogs of the fungicide fludioxonil [systematic name: 4-(2,2-difluoro-1,3-benzodioxol-4-yl)-1H-pyrrole-3-carbonitrile], contains two independent mol-ecules, A and B. The benzene and pyrrole rings are inclined to each other at 38.5 (1) and 29.3 (1)° in mol-ecules A and B, respectively. In the crystal, bifurcated N-H⋯(O,O) hydrogen bonds link A mol-ecules into chains along [001], while B mol-ecules are linked into layers parallel to the bc plane via bifurcated N-H⋯(N,N) hydrogen bonds.
