Indium(III) hydroxide is the chemical compound with the formula In(OH)3.
[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.
[8] Dissolving indium(III) hydroxide in strong alkali gives solutions that probably contain either four coordinate [In(OH)4]− or [In(OH)4(H2O)]−.
[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.
[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.
