A novel lead(II) porous metal-organic framework constructed from a flexible bifunctional macrocyclic polyamine ligand

A novel porous metal-organic framework [Pb2(TETA)]·6H2O (1) has been prepared by hydrothermal reaction of lead(II) with a flexible bifunctional macrocyclic ligand. The 1D PbO chains are cross-linked via the 14-membered macrocyclic rings of TETA4 − ligands in two different directions to form 3D framework with highly solvent accessible volume.
