Evidence for the characterisation of the C-H⋯π interaction as a weak hydrogen bond: Toluene and chlorobenzene solvates of 2,3,7,8-tetraphenyl-1,9,10-anthyridine

Abstract

The crystal structures of the toluene and chlorobenzene solvates of 2,3,7,8-tetraphenyl-1,9,10-anthyridine are nearly identical save for differences in the mode of solvent inclusion; these differences have an important bearing on the nature of the C-H⋯π interactions in these structures.
