Novel 3D LnIII−CuI 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.
