Reversible guest molecule encapsulation in the 3-D framework of a heteropolynuclear luminescent Zn4Eu2 cage complex

Guest molecules of diethyl ether or methanol are reversibly encapsulated in cavities formed by the 3-dimensional supramolecular framework of heteropolynuclear, luminescent [Eu2Zn4L4(OAc)(6)(NO3)(2)(OH)(2)] center dot 2Et(2)O.
