Syntheses and characterization nano-structured bismuth(III) oxide from a new nano-sized bismuth(III) supramolecular compound

摘要

Nano-particles of a new Bi(III) supramolecular compound, {Bi-2(mu-4,4'-bipy)Cl-10] center dot 2(4,4 '-Hbipy) center dot (4,4'-H(2)bipy) center dot 2H(2)O} (1) (4,4'-bipy = 4,4'-bipyridine), were synthesized by a sonochemical method. The nano-material was characterized by scanning electron microscopy, X-ray powder diffraction (XRD), IR spectroscopy and elemental analyses. Crystal structure of compound 1 was determined by X-ray crystallography. Calcination of the nano-particles of compound 1 at 400 degrees C under air atmospheres yields nanosized particles of alpha-Bi2O3.
