Iridium acetylacetonate are iridium coordination complex with the formula Ir(O2C5H7)3, which is sometimes known as Ir(acac)3. The molecule has D3-symmetry. It is a yellow-orange solid that is soluble in organic solvents. Two isomers are known, both prepared from IrCl3(H2O)3 and acetylacetone. Procedures exist that favor the O6-isomer and the C-bonded form.

C-bonded isomer
A second isomer of Iridium acetylacetonate is also known. In this isomer, two of the acetylacetonate ligands are bonded to Ir through carbon.
Uses
The O6-bonded isomer has been investigated for use chemical vapor deposition (CVD). One example is the deposition of red phosphorescent emitter compounds used in OLEDS.
The C-bonded isomer has been investigated as a catalyst for C-H activation reactions.
