Crystal structure of (E)-2-(4-meth-oxy-styr-yl)-3-methyl-1-phenyl-sulfonyl-1H-indole

Abstract

In the title compound, C24H21NO3S, the dihedral angles between the indole ring system (r.m.s. deviation = 0.030 Å) and the sulfur and ethyl-ene-bonded benzene rings are 80.2 (2) and 49.29 (15)°, respectively. The dihedral angle between the pendant benzene rings is 37.7 (2)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and weak C-H⋯π and π-π [centroid-to-centroid distances = 3.549 (2) and 3.743 (3) Å] inter-actions, forming a three-dimensional network.

Keywords: 1H-indole; C—H⋯π inter­actions; crystal structure; hydrogen bonding; phenyl­sulfon­yl; π–π inter­actions.
