3-(4-Chlorobutyl)-3H-indole-5-carbonitrile

In the title compound, C13H12ClN2, the indole moiety and the chloroalkyl substituent are nearly coplanar, making a dihedral angle of 1.27 (10)°. In the crystal, a supramolecular sheet parallel to the ab plane is generated via weak C—H...Cl hydrogen bonds, aromatic π–π stacking [centroid–centroid distances of 3.5563 (13) and 3.6792 (13) Å] and C—H...π interactions
