2-(4-Fluorophenyl)-3-methyl-1H-indole

Abstract

The indole N—H hydrogen in the title compound, C15H12FN, does not display classical hydrogen bonding. Rather it forms an interaction with the π system of an adjacent indole, resulting in weakly inter­acting chains along the [001] direction.

Different N—H...π interactions in two indole derivatives

“…The presence of N-HÁ Á Á interactions in indole complexes with aromatic species has been investigated by IR spectroscopy (Muñ oz et al, 2004), and such bonds have also been observed in many crystal structures of indole derivatives (e.g. Krishna et al, 1999;Cordes et al, 2011).…”
