Rhodium(III) 2,4-pentanedionate (Cat No.: M065978), commonly known as rhodium(III) acetylacetonate or Rh(acac)₃, is a coordination compound where a rhodium(III) ion is chelated by three acetylacetonate (acac) ligands. It typically appears as a dark red to brown crystalline solid and is soluble in organic solvents. This complex is used as a catalyst precursor in organic synthesis, particularly for hydrogenation, hydroformylation, and polymerization reactions. Its thermal stability and defined geometry make it valuable in organometallic chemistry, homogeneous catalysis, and the development of rhodium-based functional materials.
