1-(4-{2-[(E)-3-(4-Chloro-phen-yl)-3-oxo-prop-1-en-1-yl]phen-oxy}but-yl)-1H-indole-3-carbaldehyde.

In the title compound, C(28)H(24)ClNO(3), 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 mol-ecular structure is stabilized by a weak intra-molecular C-H⋯O inter-action. In the crystal, pairs of C-H⋯O hydrogen bonds link the mol-ecules into inversion dimers with an R(2) (2)(14) motif.
