Indium(III) hydroxide

Indium(III) hydroxide is the chemical compound with the formula In(OH)3. Its prime use is as a precursor to indium(III) oxide, In2O3.[1] It is sometimes found as the rare mineral dzhalindite.

Structure edit

Indium(III) hydroxide has a cubic structure, space group Im3, a distorted ReO3 structure.[2][3]

Preparation and reactions edit

Neutralizing a solution containing an In3+ salt such as indium nitrate (In(NO3)3) or a solution of indium trichloride (InCl3) gives a white precipitate that on aging forms indium(III) hydroxide.[4][5] A thermal decomposition of freshly prepared In(OH)3 shows the first step is the conversion of In(OH)3·xH2O to cubic indium(III) hydroxide.[4] The precipitation of indium hydroxide was a step in the separation of indium from zincblende ore by Reich and Richter, the discoverers of indium.[6]

Indium(III) hydroxide is amphoteric, like gallium(III) hydroxide (Ga(OH)3) and aluminium hydroxide (Al(OH)3), but is much less acidic than gallium hydroxide (Ga(OH)3),[5] having a lower solubility in alkaline solutions than in acid solutions.[7] It is for all intents and purposes a basic hydroxide.[8]

Dissolving indium(III) hydroxide in strong alkali gives solutions that probably contain either four coordinate [In(OH)4] or [In(OH)4(H2O)].[8]

Reaction with acetic acid or carboxylic acids is likely to give the basic acetate or carboxylate salt, e.g. (CH3COO)2In(OH).[7]

At 10 MPa pressure and 250-400 °C, indium(III) hydroxide converts to indium oxide hydroxide (InO(OH)), which has a distorted rutile structure.[5]

Rapid decompression of samples of indium(III) hydroxide compressed at 34 GPa causes decomposition, yielding some indium metal.[9]

Laser ablation of indium(III) hydroxide gives indium(I) hydroxide (InOH), a bent molecule with an In-O-H angle of around 132° and an In-O bond length of 201.7 pm.[10]
