Applications include their use as NMR "shift reagents" and as catalysts for organic synthesis, and precursors to industrial hydroformylation catalysts. C 5 H 7 O − 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).
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, which can be obtained in anhydrous form from direct oxidation of iridium powder by chlorine at 650 °C, [15] or in hydrated form by dissolving Ir 2 O 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 ...
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 ...
Ruthenium(III) acetate, commonly known as basic ruthenium acetate, [1] describes a family of salts where the cation has the formula [Ru 3 O(O 2 CCH 3) 6 (OH 2) 3] +.A representative derivative is the dihydrate of the tetrafluoroborate salt [Ru 3 O(O 2 CCH 3) 6 (OH 2) 3]BF 4 (H 2 O) 2, which is the source of the data in the table above.

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.
There are a few divalent and trivalent aqua ions of transition metals in the second and third transition series: ruthenium(II) and (III), rhodium(III), and iridium(III), all octahedral. (Ruthenium and iridium structures have only been examined in the solid state, but it is assumed that they are the same in aqueous solution.) [27] Molybdenum(III ...
