One-Dimensional Barium Coordination Polymer With 2,2'-Bipyridine-5,5'-Dicarboxylate Ligand: Synthesis, Spectroscopic Characterization, Thermal Analyses, and Crystal Structure.

[Ba(5,5´-dcbipy)(μ-H2O)2(H2O)2]n(1) complex was obtained from the reaction of one equivalent of 2,2'-bipyridine-5,5'-dicarboxylic acid (5,5´-dcbipy.H2) and one equivalent of ethylene diamine (en) with one equivalent of BaCl2.2H2O in water. This complex was characterized by elemental analysis, IR, UV-Vis, and luminescence spectroscopy and its structure was studied by the single-crystal X-ray diffraction method. The thermal stability of1was studied by thermogravimetric and differential thermal analyses. [ABSTRACT FROM AUTHOR]
