Шаблон:Chembox Indium(III) nitrate is a nitrate salt of indium which forms various hydrates. Only the pentahydrate has been crystallographically verified. Other hydrates are also reported in literature, such as the trihydrate.[1][2][3]

Production and reactions

Indium(III) nitrate hydrate is produced by the dissolution of indium metal in concentrated nitric acid followed by evaporation of the solution:[1][2][3]

In + 4 HNO3 → In(NO3)3 + NO + 2 H2O

The hydrate first decomposes to a basic salt and then to indium(III) oxide at 240 °C. Anhydrous indium(III) nitrate is claimed to be produced by the reaction of anhydrous indium(III) chloride and dinitrogen pentoxide.[2][4]

In the presence of excess nitrate ions, indium(III) nitrate converts to the [In(NO3)4] ion.[1][2]

The hydrolysis of indium(III) nitrate yields indium(III) hydroxide. It also reacts with sodium tungstate to form In(OH)WO4, [In(OH)2]2WO4, NaInWO4 or In2(WO4)3 depending on pH.[5][6]

Structure

Only the pentahydrate has been structurally elucidated. The pentahydrate consists of octahedral [In(NO3)(H2O)5]2+ centers as well as two nitrates and is monoclinic.[1]
