A Bismuth(III) Coordination Polymer With Pyridine-2,3-dicarboxylic Acid as Precursor for Preparation of Bi₂O₃ Nanoparticles via Thermal Decomposition

Abstract

A novel 1D-Bismuth(III) coordination polymer, {(4-Hmapy)[(μ-2,3-pydc)(2,3-pydcH)Bi(NO₃)].2H₂O}n (1) (pydc H₂ = pyridine-2,3-dicarboxylic acid, 4-mapy = 2-amino-4-methylpyridine) has been synthesized and characterized by elemental analysis and IR spectroscopy as well as by X-ray structure analysis. Thermal decomposition of 1 in the peresence of polyethylene glycol led to nanoparticles of Bi₂O₃. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the structure and morphology of synthesized powder. The powder XRD pattern established the formation of Bi₂O₃ with α polymorph structure.

Keywords:
