摘要：

Reaction of a flexible pyridinecarboxamide ligand N,N'-[(2,3,5,6-tetrafluoro-1,4-phenylene) bis(methylene)]bis(pyridine-4-carboxamide) (H(2)tfpbbp) with Cu-II chloride or perchlortate affords two coordination polymers {[Cu(H(2)tfpbbp)(tfpbbp)(H2O)] center dot 2DMF center dot 4H(2)O}(n) (1) and {[Cu(H(2)tfpbbp)(2)(ClO4)(2)] center dot 3H(2)O}(n) (2). Both complexes have 2-D (4,4) layered networks extended by the exo-bidentate bridging ligands, which however consist of distinct [Cu-ligand](4) meshes owing to the conformational difference of ligands. Their spectroscopic, thermal, and fluorescence properties have also been investigated. (C) 2008 Elsevier B.V. All rights reserved.
