Indium Acetylacetonate – a colorless solid

Indium acetylacetonate, also known as In(acac)3, is a compound with formula In(C5H7O2)3. It is a colorless solid. It adopts an octahedral structure. It consists of indium ions coordinated to three acetylacetonate ligands (acac). It can act as a catalyst in organic reactions. It is used in the production of indium oxide films for electronic applications. It serves as a precursor for the synthesis of indium-containing materials.

The compound is typically a solid at room temperature and can be soluble in organic solvents. Safety precautions should be taken when handling it, as with other chemical compounds.

Properties

Indium acetylacetonate features indium ions coordinated to three acetylacetonate ligands. The acetylacetonate acts as a bidentate ligand, coordinating through its oxygen atoms. It typically appears as a solid, often yellowish in color. It is soluble in organic solvents like ethanol, acetone, and toluene but less soluble in water.
