A three-dimensional Bi(III) based metal-organic framework was synthesized under hydrothermal conditions using the multidentate organic linker 3,5-pyridinedicarboxylate. Bismuth oxide 3,5-pyridinedicarboxylate, Bi2O2[NC5H3(CO2)(2)], contains embedded 1-D cationic bismuth oxide chains that propagate along the crystallographic c-axis. The oxygens of the Bi2O2 core are three-coordinate and bond strongly to the Bi atoms. Thermogravimetric analysis shows that the material possesses high thermal stability up ca. 400 degrees C before decomposing to phase-pure Bi2O3 at 800 degrees C. The structure, crystallinity, morphology and properties of the material are discussed. Published by Elsevier B.V.
