Steric interactions in 1,3-dicarboxamidoanthraquinones have been employed to âtwistâ isophthalamide-like anion binding sites; the crystal structure of the fluoride complex of a bis-3,5-dichlorophenylamide derivative shows the receptor acting as a âhydrogen-bonding cornerâ in a â2 + 2â fluoride containing molecular box.
