摘要：

Pyridine-2,6-dicarboxylic acid reacts as the first ligand under hydrothermal conditions with divalent cobalt ions to form three 1D polymeric complexes in the presence of 2,4'-bipyridine as well as its derivatives 5-phenyl-2,4'-bipyridine or 5-(4-bromophenyl)-2,4'-bipyridine as the second ligands. The structures and properties of these complexes are characterized by X-ray crystallography, variable temperature magnetic measurements, infrared and thermal gravimetric analyses. It was found that the antiferromagnetic interactions between the Con ions can be tuned by the substituent on the second ligand. (c) 2007 Elsevier Ltd. All rights reserved.
