Structural and zeolitic features of a 3D heterometallic porous architecture constructed from a {M(oxalate)4}4- building unit.

The utilization of the tetrahedral pre-formed coordination compound {U(C(2)O(4))(4)}(4-) permitted the efficient synthesis of a 3D heteronuclear supramolecular nano-porous architecture undergoing a reversible sorption process without collapsing.
