title: Crystal structure of methyl (2Z)-3-(4-chloro-phen-yl)-2-[(3-methyl-1H-indol-1-yl)meth-yl]prop-2-enoate.
abstract: In the title indole derivative, C20H18ClNO2, the chloro-phenyl ring is almost perpendicular to the indole moiety, making a dihedral angle of 87.6 (1)°. The mol-ecular packing is stabilized by C-H⋯π inter-actions, which form a C(9) chain motif along [10-1]. In addition, there are weak π-π inter-actions [centroid-centroid distance 3.851 (1) Å] between the chains, involving inversion-related chloro-phenyl rings.
