2 in some cases also binds to metals through the central carbon atom ; this bonding mode is more common for the third-row transition metals such as platinum(II) and iridium(III). The complexes Ir(acac) 3 and corresponding Lewis-base adducts Ir(acac) 3 L (L = an amine ) contain one carbon-bonded acac ligand.
Iridium acetylacetonate is the iridium coordination complex with the formula Ir(O 2 C 5 H 7) 3, which is sometimes known as Ir(acac) 3. The molecule has D 3 -symmetry. [ 2 ] It is a yellow-orange solid that is soluble in organic solvents.
Indium acetate is an acetate of indium, with the chemical formula In(CH 3 COO) 3. It is soluble in water, acetic acid and mineral acids. [ 1 ] It is the precursor of indium-containing compounds such as the solar cell materials CuInS 2 [ 2 ] and indium phosphide quantum dots .
3 in hydrochloric acid, is often used as a starting material for the synthesis of other Ir(III) compounds. [2] Another compound used as a starting material is ammonium hexachloroiridate(III), (NH 4) 3 IrCl 6. In the presence of air, iridium metal dissolves in molten alkali-metal cyanides to produce the Ir(CN) 3− 6 (hexacyanoiridate) ion.
Organoiridium compounds share many characteristics with those of rhodium, but less so with cobalt. Iridium can exist in oxidation states of -III to +V, but iridium(I) and iridium(III) are the more common. iridium(I) compounds (d 8 configuration) usually occur with square planar or trigonal bipyramidal geometries, whereas iridium(III) compounds (d 6 configuration) typically have an octahedral ...

Indium acetylacetonate and tin(II) acetylacetonate can be used to prepare indium tin oxide thin films with an atmospheric‐pressure chemical vapor deposition method. The resulting thin films are transparent and conductive, with a thickness of about 200 nanometers. [3]
An example of a homogeneous catalytic system is the reductive amination of ketones done with an iridium catalyst. [20] Homogenous Iridium (III) catalysts have been shown to be effective in the reductive amination of carboxylic acids, which in the past has been more difficult than aldehydes and ketones. [16]
