In the title compound, C36H24Br3N3O6·C7H8, the toluene solvent molecule is associated with the receptor molecule via C—Hπ bonding. The planes of the phthalimido groups are inclined at 77.0 (1), 63.0 (1) and 77.8 (1)° with respect to the benzene ring. The molecular conformation is stabilized by C—HO and C—HBr hydrogen bonds. The crystal structure features non-classical hydrogen bonds of the C—HN, C—HO and C—HBr type, leading to a three-dimensional cross-linking of molecules. The pattern of non-covalent intermolecular bonding is completed by OBr halogen bonds [3.306 (3) Å], which link the receptor molecules into infinite strands extending along the a-axis direction.
