摘要

A new nanostructured Bi(III) supramolecular compound, {[Bi2(4,40-Hbipy)1.678(4,40-Hbipy)0.322(l-I)2I5.678](4,40-bipy)} (1), 4,40-bipy = 4,40-bipyridine} was synthesized by a sonochemical method. The nano-structure of 1 was investigated using scanning electron microscopy, powder X-ray powder diffraction (XRD),IR spectroscopy and elemental analysis, and the crystal structure of compound 1 was determined by single-crystal X-ray diffraction. The thermal stability of bulk compound 1 and of nano sized particles was studied by thermal gravimetric (TG) and differential thermal analyses (DTA). Bi2O3 and BiI3 nano-structures were obtained by calcinations of nano-structures of compound 1 at 400 C under air and nitrogen atmospheres,respectively.
