Abstract: | Nanoparticles of a Bi(III) coordination polymer, {[Bi(μ-4,4′-bipy)Br4] · (4,4′-Hbipy)} n (1) (4,4′-bipy = 4,4′-bipyridine), were synthesized by a sonochemical method. The new nanoparticles were characterized by scanning electron microscopy, X-ray powder diffraction (XRD), IR spectroscopy, and elemental analyses. Compound 1 was structurally characterized by single-crystal X-ray diffraction. The thermal stabilities of 1 as bulk and at nanosize were studied by thermal gravimetric (TG) and differential thermal analyses (DTA). The Bi2O3 and BiBr3 nanostructures were obtained by calcinations of nanostructure of 1 in air and argon. |
