Bidirectional Regulation of Halide Binding in a Heterometallic Supramolecular Cube

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 (CF3CO2−, OPMe3, NH3, or NMe3) either cooperatively enhanced or competitively inhibited...

Description
Summary: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 (CF3CO2−, OPMe3, NH3, or NMe3) either cooperatively enhanced or competitively inhibited the binding of a second guest (halide ion).
