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

Abstract

[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 of 1 was studied by thermogravimetric and differential thermal analyses.
