Two three-dimensional coordination polymers of lead(II) with iminodiacetate and naphthalene-dicarboxylate anions: Synthesis, characterization and luminescence behavior

Two lead(II) compounds [Pb3(idiac)3(phen)2(H2O)] . 2(H2O) (1) and [Pb(ndc)]n (2), where H2idiac = iminodiacetic acid, phen = 1,10-phenanthroline and H2ndc = naphthalene-2,6-dicarboxylicacid ,have been synthesized and structurally characterized. Singlecrystal X-ra ydiffraction analysis showed that compound 1 is adiscrete trinuclear complex (of two-fold symmetry) which evolves to a supramolecular 3D network via π–π interactions, while i ncompound 2 the naphthalene dicarboxylate anion act as a linker to form a three dimensional architecture, where the anion adopts a bis-(bidentatebridging) coordination mode connecting four Pb(II) centers.The photoluminescence property of the two complexes hasbeenstudied.
