Abstract: Three new haloplumbates(II)/aromatic N-heterocyclic organic hybrids, [(nmp)(PbI3)] n (nmp= N-methylpyrazine)(1), [(dhpp)(Pb2Cl6)] n (dhpp=6,12-dihydrodipyrido[1,2-a:1′,2′-d] pyrazinium)(2), [(dedp)3(Pb6I18)] n (dedp= N,N′-diethyl-4,4′-dipyridinium)(3) have been synthesized and structurally determined. These polymeric haloplumbates exhibit different model type structures, including one-dimensional linear chain (for 1), ribbonlike arrangement based on face- and edge-sharing PbX n tetragonal pyramids or octahedra (for 2 and 3), and N-heterocyclic organic cations weakly interact with inorganic haloplumbates to present 3-D supramolecular networks. Three compounds posses semiconducting properties with Eg ranging among 2.07–2.71eV. Photoluminescence and third-order nonlinear optical (NLO) activity of 3 were also discussed.
