摘要
Reactions of metal acetates with 4-amino-3,5-bis(3-pyridyl)-1,2,4-triazole (3-abpt) and co-ligands gave rise to four new complexes, namely [Zn-2(3-abpt)(beta)(DMF) (H2O)(2)](n) nH(2)O (1), [Zn(3-abpt)(1p)](n) 3nH(2)O (2), [Zn(3-abpt)(1p)(H2O)(2)](n) 2nH(2)O (3), and [Cu-2(3-abpt)(2)(C6H5COO)(4)(H2O)(2)](n) 2nH(2)O (4) (ip = isophthalate, beta = 1,2,4,5-benzenetetracarboxylate). Compound 1 is a 3D coordination polymer with uncommon 3,4-connected (6(2),8)(2)(6(2),8(2) 10(2)) network Compounds 2-4 are all 1D coordination polymers, which exhibit diversity structures Compound 2 is a tubular-like chain. 3 is a ring-like network, and 4 is a zigzag chain. Their thermal stabilities and the photoluminescence of 1 have also been investigated. (C) 2009 Elsevier Ltd. All rights reserved.
