Syntheses, structures and thermal stabilities of four complexes with 4-amino-3,5-bis(3-pyridyl)-1,2,4-triazole ligand
摘要:
Reactions of 4-amino-3,5-bis(3-pyridyl)-1,2,4-triazole (3-abpt) with metal acetates gave rise to four new complexes [Cu(3-abpt)(ip)](n) center dot 2nH(2)O (1), [Co(3-abpt)(ip)(H2O)(2)](n)center dot 2nH(2)O (2), [Ni(3-abpt)(tp)(H2O)(2)](n) (3) and [Cu(3-abpt)(2)(CH3COO)(2)(H2O)(2)] (4) (ip = isophthalate, tp = terephthalate), which were characterized by EA, IR and X-ray crystallography. Compound I consists of two kinds of ring-like chain which are interconnected to form an unusual two-dimensional layered motif. Compounds 2 and 3 are both I D ring-like infinite chains. Compound 4 is a mononuclear complex. The thermal stabilities of coordination polymers 1-3 have been investigated. (c) 2008 Elsevier B.V. All rights reserved.
