Synthesis and characterization of one lead(II) photoluminescent coordination polymer with the fumarate ligand

One lead(II) photoluminescent coordination polymer, [Pb(fum)(Phen)·2H2O]n (fum = fumarate, phen = 1,10-phenanthroline), has been synthesized. The complex shows a novel center-symmetrical dinuclear-based 2D architecture and further assembles into porous 3D supramolecular framework with 1D channels via interlayer π-π stacking interactions. The six-coordinated lead atoms show hemidirected geometry.
