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 [Zn2(3-abpt)(beta)(DMF) (H2O)2]n·nH2O (1), [Zn(3-abpt)(ip)]n·3nH2O (2), [Zn(3-abpt)(ip)(H2O)2]n·2nH2O (3), and [Cu2(3-abpt)2(C6H5COO)4(H2O)2]n·2nH2O (4) (ip = isophthalate, beta = 1,2,4,5-benzenetetracarboxylate). Compound 1 is a 3D coordination polymer with uncommon 3,4-connected (62.8)2(62.82.102) 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.
