Hydrolysis of a Basic Bismuth Nitrate—Formation and Stability of Novel Bismuth Oxido Clusters

“…[1,4] Nevertheless, today the use of bismuth subnitrate is declining, but it is still used as a pharmaceutical ingredient, for example for the eradication of helicobacter pylori in the bismuth-based triple therapy, especially in developing countries. [5] So-called bismuth subnitrate is commercially available as bismuthA C H T U N G T R E N N U N G (III) oxido hydroxo nitrate with an ascribed formula of Bi 5 O(OH) 9 A C H T U N G T R E N N U N G (NO 3 ) 4 , which is obtained by hydrolysis of aqueous bismuthA C H T U N G T R E N N U N G (III) nitrate solution and is likely a mixture of various compounds such as BiONO 3 , BiA C H T U N G T R E N N U N G (NO 3 )(OH) 2 , and BiOOH. [2,6] A variety of different basic bismuth nitrates have been reported in the literature but only a few of them are fully characterized.…”

“…[7,8] Starting from aqueous bismuth nitrate solution different polynuclear, mainly hexanuclear, basic bismuth nitrates were obtained. [7][8][9][10] Their formation is assumed to result from intramolecular polycondensation of hydrated Bi 3 + ions. [11] Up to now the highest nuclearity of bismuth oxido nitrates observed after hydrolysis of BiA C H T U N G T R E N N U N G (NO 3 ) 3 was found in [Bi 6 O 5 (OH) 3 ] 2 A C H T U N G T R E N N U N G (NO 3 ) 10 , which consists of two linked [Bi 6 O 8 ] 2 + subunits, [9] but larger aggregates are likely to be formed in the course of the formation of Bi 2 O 3 upon hydrolysis.…”

Anionic Bismuth-Oxido Carboxylate Clusters with Transition Metal Countercations

“…5,6 Bismuth-oxido clusters have drawn attention from several groups, as they highlight bismuth's ability to form large, multinuclear oxido complexes. [7][8][9][10][11][12][13][14][15][16][17][18] These clusters are readily synthesized via hydrolysis of the bismuth(III) compounds and can be used as precursors for bismuth-based solid state materials applications. [19][20][21] Bismuth compounds have long been known to undergo hydrolysis.…”

“…Bismuth is a useful component of many drugs with potential for diverse chemical and biological applications. − Its unique properties along with its nontoxicity has led bismuth to be utilized in alloys, nontoxic pigments, thermoelectric and ferroelectric materials, and catalysts. , Bismuth-oxido clusters have drawn attention from several groups, as they highlight bismuth’s ability to form large, multinuclear oxido complexes. − These clusters are readily synthesized via hydrolysis of the bismuth­(III) compounds and can be used as precursors for bismuth-based solid state materials applications. − …”
