摘要：

Three Cu(II) coordination polymers [Cu(taa)(2)](n) (1), [Cu(taa)(2) center dot (H2O)(4) center dot Na-0.5 center dot (ClO4)(0.5)](n) (2) and [Cu(taa)(2) center dot (H2O)(4) center dot Na-0.5 center dot (BF4)(0.5)](n) (3) have been synthesized by the reaction of 1H-1,2,4-triazol-1-acetic acid (Htaa) with different Cu(II) salts. Polymer 1 features a 2-D grid-like network structure constructed by crossed zigzag chains. In both of polymers 2 and 3, there exist rare four-fold 1-D helical chains, which are induced by ClO4 or BF4- anions. Besides, trapped sodium chains are found to be nested in the channels formed by the intertwist of the helical chains of 2 and 3. (C) 2008 Elsevier B.V. All rights reserved.
