Complex cubes : In a cationic supramolecular cube, coordinatively unsaturated metal centers in the walls of the host provided binding sites for neutral or negatively charged guests. The binding of an initial guest (CF 3 CO 2 − , OPMe 3 , NH 3 , or NMe 3 ) either cooperatively enhanced or competitively inhibited the binding of a second guest (halide ion).
