Three new haloplumbates(II)/aromatic N-heterocyclic organic hybrids, [(nmp)(Pbl(3))](n) (nmp = N-methyl-pyrazine)(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 PbXn 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 E-g ranging among 2.07-2.71 eV. Photoluminescence and third-order nonlinear optical (NLO) activity of 3 were also discussed.
