Polar host–guest assembly mediated by halogen⋯π interaction: inclusion complexes of 2,4,6-tris(4-halophenoxy)-1,3,5-triazine (halo = chloro, bromo) with trihalobenzene (halo = bromo, iodo)
Abstract
Crystallization of four isomorphous host–guest complexes in the polar space group P63 is ascribed to the recurring halogen(guest)⋯π(host) interaction.
