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  direction.
The title compound has previously been prepared by Buu-Hoi & Jacquignon (1949 ▶) and by Kraus & Guo (2009 ▶). For the synthesis of the starting material, 4-fluoro-N-(2-oxo-2-phenylethyl)benzamide, see: Moriya et al. (1986 ▶). There are no structures of closely related compounds in the literature. For some similar compounds, see: Schmelter et al. (1973 ▶); Konno et al. (2004 ▶); Kumar & Liu (2006 ▶).
