Novel 3D Ln^III−Cu^I Supramolecular Architecture Based on 2D MOFs with (6,3) Topology

Three novel coordination polymers, [LnCu(PZDC)₃]·[Ln(H₂O)₉]_0.5·[(H₂O)₇H⁺]_0.5 [Ln = La (1), Eu (2), Gd (3)], were synthesized. They are the first 3d−4f heterometallic framework with supramolecular 1D channels, in which lanthanide hydrate cations and lattice water molecules are located.
