Amorphous indium oxide is insoluble in water but soluble in acids, whereas crystalline indium oxide is insoluble in both water and acids. The crystalline form exists in two phases, the cubic (bixbyite type) [1] and rhombohedral (corundum type). Both phases have a band gap of about 3 eV. [3] [4] The parameters of the cubic phase are listed in ...
Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Aluminium oxide (Al 2 O 3) is an example of an amphoteric oxide. Amphoterism depends on the oxidation states of the oxide. Amphoteric oxides include lead(II) oxide and zinc oxide, among many others. [5]
Boron oxide (B 2 O 3) is slightly acidic, aluminium and gallium oxide (Al 2 O 3 and Ga 2 O 3 respectively) are amphoteric, indium(III) oxide (In 2 O 3) is nearly amphoteric, and thallium(III) oxide (Tl 2 O 3) is a Lewis base because it dissolves in acids to form salts. Each of these compounds are stable, but thallium oxide decomposes at ...
Indium(I) compounds are not common. The chloride, bromide, and iodide are deeply colored, unlike the parent trihalides from which they are prepared. The fluoride is known only as an unstable gas. [42] Indium(I) oxide black powder is produced when indium(III) oxide decomposes upon heating to 700 °C. [38]

A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds, or some combination of these effects.
Numerous investigations have found an explanation for this effect. The oxygens of the carbonyl and the hydroxyl group chelate the indium of the organoindium intermediate as illustrated below on the left by the two green bonds. The incipient C-C bond, illustrated in red, creates a six-member ring in a chair conformation.
