Indium(III) nitrate is anitrate salt ofindium 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]
Indium(III) nitrate hydrate is produced by the dissolution of indium metal in concentratednitric acid followed by evaporation of the solution:[1][2][3]
The hydrate first decomposes to a basic salt and then toindium(III) oxide at 240 °C. Anhydrous indium(III) nitrate is claimed to be produced by the reaction of anhydrousindium(III) chloride anddinitrogen 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 yieldsindium(III) hydroxide. It also reacts withsodium tungstate to form In(OH)WO4, [In(OH)2]2WO4, NaInWO4 or In2(WO4)3 depending on pH.[5][6]
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]
