2,2-Bis(1H-indol-3-yl)indolin-3-one

Abstract

In the title molecule, C24H17N3O, the mean plane of the indolone ring forms dihedral angles of 112.0 (1) and 103.1 (1)° with the planes of the two indole rings. The dihedral angle between the mean planes of the two indole rings is 63.5 (1)°. In the crystal structure, molecules are linked via intermolecular N—H...O hydrogen bonds, forming a two-dimensional network parallel to the ab plane.
