1-(4-{2-[(E)-3-(4-Chloro­phen­yl)-3-oxo­prop-1-en-1-yl]phen­oxy}but­yl)-1H-indole-3-carbaldehyde

In the title compound, C₂₈H₂₄ClNO₃, the dihedral angles between the central benzene ring and the indole ring system and the chlorobenzene ring are 70.81 (5) and 78.62 (5)°, respectively. The mol­ecular structure is stabilized by a weak intra­molecular C—H...O inter­action. In the crystal, pairs of C—H...O hydrogen bonds link the mol­ecules into inversion dimers with an R₂²(14) motif.
