Synthesis, Crystal Structure and Luminescent Property of a Three-Dimensional Framework Zinc Coordination Polymer Constructed from the Benzenemulticarboxylic Acid and N-donor Ligands

A novel coordination polymer, [Zn-3(BTCA)(2)(4,4'-bipy)(2)](1) (BTCAH(3)=5-bromobenzene-1,2,4-tricarboxylic acid, 4,4'-bipy=4,4'-bipyridine) has been synthesized utilizing Zn(OAc)(2)center dot 2H(2)O, the rigid 5-bromobenzene-1,2,4-tricarboxylic acid and 4,4'-bipy under the hydrothermal reaction. Compound 1 was characterized by infrared spectroscopy, elemental analysis, thermogravimetric analysis and single crystal X-ray diffraction analysis. In 1, the Zn(II) ions are linked through the carboxylate oxygen atoms of the BTCA(3-) anions, forming a three-dimensional framework structure with 3-nodal and 4-connected net with Schlafli symbol of (4.7.8(4))(2)(4.7(4).8)(2)(7(4).8(2)). The 4,4'-bipy ligand coordinates the Zn (II) ions in the framework. In addition, the thermal stability and luminescent properties of compound 1 were also investigated in this paper. CCDC: 811925.
