Crystal structure of methyl (2Z)-3-(4-chlorophenyl)-2-[(3-methyl-1H-indol-1-yl)methyl]prop-2-enoate

Abstract

In the title indole derivative, C20H18ClNO2, the chlorophenyl ring is almost perpendicular to the indole moiety, making a dihedral angle of 87.6 (1)°. The molecular packing is stabilized by C—H...π interactions, which form aC(9) chain motif along [10-1]. In addition, there are weak π–π interactions [centroid–centroid distance 3.851 (1) Å] between the chains, involving inversion-related chlorophenyl rings.
