Abstract: In the molecule of the title compound, C13H10ClNO, the benzene and pyrrole rings are oriented at a dihedral angle of 7.37 (12)°. In the crystal structure, intermolecular N-HO hydrogen bonds link the molecules into centrosymmetric R22(10) dimers. There are C-H interactions between benzene and pyrrole rings and a benzene C-H group. A weak - interaction between the pyrrole rings [centroid-centroid distance 3.8515 (11) Å] further stabilizes the structure. There is also a interaction between the pyrrole ring and the carbonyl group, with a carbon-centroid distance of 3.4825 (18) Å.
