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.
Ruthenium(III) acetylacetonate is a coordination complex with the formula Ru(O 2 C 5 H 7) 3. O 2 C 5 H 7 − is the ligand called acetylacetonate. This compound exists as a dark red solid that is soluble in most organic solvents. [3] It is used as a precursor to other compounds of ruthenium.
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. [ 2 ]

The complex TiCl 2 (acac) 2 is fluxional in solution, the NMR spectrum exhibiting a single methyl resonance at room temperature. [ 6 ] Unlike Ti(IV), both Zr(IV) and Hf(IV) bind four bidentate acetylacetonates, reflecting the larger radius of these metals.
Iridium compounds are compounds containing the element iridium (Ir). Iridium forms compounds in oxidation states between −3 and +9, but the most common oxidation states are +1, +2, +3, and +4. [2] Well-characterized compounds containing iridium in the +6 oxidation state include IrF 6 and the oxides Sr 2 MgIrO 6 and Sr 2 CaIrO 6.
Iridium(III) bromide is a dark reddish-brown solid that is insoluble soluble in water, acids, and alkalis and decomposes to iridium(II) bromide on heating. [1] It crystallizes in a highly disordered layered structure of aluminum(III) chloride or chromium(III) chloride type, where the monoclinic unit cell contains four formula units .
This red brown solid is the acetate salt of the coordination complex [Fe 3 O(OAc) 6 (H 2 O) 3] + (OAc − is CH 3 CO 2 −). Commonly, the salt is known as "basic iron acetate". [ 2 ] The formation of the red-brown complex was once used as a test for ferric ions.
