1-Benzyl-3,3-dichloro-1H-indol-2(3H)-one

The title compound, C15H11Cl2NO, was synthesized from N - benzyl-isatin. The compound crystallizes as stacks of mol-ecules running down the c axis. Mol-ecules within each of these stacks inter-act with each other through π-π and C - H⋯π inter-actions, and inter-act with neighbouring stacks through C - H⋯O inter-actions. © International Union of Crystallography 2007.
