Encapsulation of a Magnesium Hydroxide Cubane by a Bowl-Shaped Polypyrrolic Schiff Base Macrocycle

Hydrolysis of a Pacman-shaped binuclear magnesium complex of a polypyrrolic Schiff base macrocycle results in the formation of a new magnesium hydroxide cubane that is encapsulated by the macrocyclic framework through both coordinative and hydrogen-bonding interactions.
