摘要：

Two novel inorganic-organic hybrid frameworks [Cu-2(BPTCA)(H2O)(2) center dot 2H(2)O](n) (1) and [Cd-2(BPTCA)(mu-OH2)(2)](n) (2) were obtained by reactions of 4,4'-bipyridine-2,2',6,6'-tetracarboxylic acid (H(4)BPTCA) with copper(II) and cadmium(II) salts, respectively and characterized by X-ray single crystal structure analysis. Complex 1 has a two-dimensional ladder-like structure containing infinite -Cu-O-chains. The magnetic susceptibility data of 1 show the intra-chain ferromagnetic exchange coupling resulting from the orthogonal arrangement of copper magnetic orbital within the -Cu-O- infinite chain. Complex 2 is a three-dimensional framework in which the -Cd-(O)(2)- zigzag-chains are linked by BPTCA(4-). The photoluminescence property of 2 is studied. (C) 2008 Elsevier B.V. All rights reserved.
