4-(2,3-Dimethoxyphenyl)-1H-pyrrole-3-carbonitrile

Abstract

The asymmetric unit of the title compound, C13H12N2O2, 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 molecules, A and B. The benzene and pyrrole rings are inclined to each other at 38.5 (1) and 29.3 (1)° in molecules A and B, respectively. In the crystal, bifurcated N—H...(O,O) hydrogen bonds link A molecules into chains along [001], while B molecules are linked into layers parallel to the bc plane via bifurcated N—H...(N,N) hydrogen bonds.
