Bismuth(III) nitrate is a salt composed of

metallic nature.[5]

Preparation and reactions

Bismuth nitrate can be prepared by the reaction of bismuth metal and concentrated nitric acid.[6]

Bi + 4HNO3 → Bi(NO3)3 + 2H2O + NO

It dissolves in nitric acid but is readily hydrolysed to form a range of oxynitrates when the pH increases above 0.[7]

It is also soluble in acetone, acetic acid and glycerol but practically insoluble in ethanol and ethyl acetate.[8]

Some uses in organic synthesis have been reported for example the nitration of aromatic compounds and selective oxidation of sulfides to sulfoxides.[8]

Bismuth nitrate forms insoluble complexes with pyrogallol and cupferron and these have been the basis of gravimetric methods of determining bismuth content.[9]

On heating bismuth nitrate can decompose forming nitrogen dioxide, NO2.[10]

Structure

The crystal form is triclinic, and contains 10 coordinate Bi3+, (three bidentate nitrate ions and four water molecules).[1]
