Abstract

In the mol-ecule of the title compound, C(13)H(10)ClNO, the benzene and pyrrole rings are oriented at a dihedral angle of 7.37 (12)°. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(10) dimers. There are C-H⋯π inter-actions between benzene and pyrrole rings and a benzene C-H group. A weak π-π inter-action between the pyrrole rings [centroid-centroid distance 3.8515 (11) Å] further stabilizes the structure. There is also a π inter-action between the pyrrole ring and the carbonyl group, with a carbon-centroid distance of 3.4825 (18) Å.
