The self-assembly of pyrazine-2-carboxylate and oxalate with mixed-metal salts under hydrothermal conditions gave three isostructural 3D 4d-4f coordination polymers, LnAg(ox)(2-pzc)2 · H2O [Ln = Eu (1); Tb (2); Dy (3)] [ox = oxalate, 2-pzc = pyrazine-2-carboxylate]. All three structures exhibit same unusual 3D nanoporous heterometallic coordination frameworks constructed by zigzag lanthanide–oxalate chains and Ag(2-pzc)2 units. Furthermore, the luminescent properties of complexes 1 and 2 are discussed.
Three unusual 3D 4d–4f coordination polymer, LnAg(ox)(2-pzc)2·H2O [Ln = Eu (1); Tb (2); Dy (3)] [ox = oxalate, 2-pzc = pyrazine-2-carboxylate] has been hydrothermal synthesized and characterized. All three structures exhibit same unusual 3D nanoporous heterometallic coordination frameworks constructed by helical lanthanide–oxalate chains and Ag(2-pzc)2 units. They represent the first examples of 3D 4d–4f heterometallic open coordination frameworks by spontaneous assembly.Figure optionsDownload full-size imageDownload as PowerPoint slide
