Abstract: Reactions of different metal salts with 4-amino-3,5-bis(3-pyridyl)-1,2,4-triazole (3-abpt) gave rise to five new complexes, namely [Cu4(CN)4(3-abpt)2] n (1), [CuBr(3-abpt)] n (2), [CuI(3-abpt)] n (3), [Cu3I3(3-abpt)] n (4) and [Cu(3-abpt)(SO4)(H2O)] n (5). Compounds 1, 3, 4 and 5 are all 2D structures. Compound 1 is a double-layered polymer with an uncommon 3-nodal 3-connected (103)(102.4)4 network, 3 shows a 2D square layered structure, 4 is also a double-layered polymer with 2-nodal 4-connected (3.4.5.62.7)2(3.42.52.7) network and 5 is a 2D structure which is ultimately stacked with an ABAB repeat pattern. Compound 2 is a 1D coordination polymer which exhibits a ladder-like network. The photoluminescence of 1–2 has also been investigated. The long emission lifetimes of 1–2 could be assigned to metal-to-ligand charge transfer triple excited states [MLCT]. [Copyright &y& Elsevier]
