Metal-organic frameworks for selective separations

A 3D porous metal-organic framework and method of making are described. In some embodiments, a 3D porous metal-organic framework may be based on a trinodal (3,3,4) net of zyg topology by the self-assembly of the nonlinear hexacarboxylate (BHB) with the paddle-wheel Cu(COO)cluster.
