Synthesis and characterization of a novel three-dimensional photoluminescent coordination polymer generated from unsymmetrically bridging ligand

A novel three-dimensional metal-organic coordination polymer, [Zn-2(HBTC)(2)(H2O)(3)](n) (1) (BTC = 1,2,4-benzenetricarboxylate), has been prepared by aqueous solution reaction of Zn(NO3)(2) . 6H(2)O and BTC at moderate temperature and characterized by IR, TGA and single-crystal X-ray diffraction analysis. The three-dimensional architecture of 1 not only possesses rectangular cavities but also has ordered one-dimensional straight channels. Furthermore, compound 1 shows intense photoluminescent property at room temperature. (C) 2004 Elsevier B.V. All rights reserved.
