Dimethylindium acetylacetonate (dimethyl(pentane-2,4-dionato)indium(III)), [InMe2(acac)]2 was synthesized as crystalline solid by the reaction of dimethylindium methoxide and acetylacetone in toluene. The compound is dimeric in the solid state according to the single crystal XRD.
[InMe2(acac)]2 as been applied as a single-source precursor for the deposition of single phase cubic In2O3 layers on borosilicate glass, Si(100) and GaAs(111) substrates at 350-450 °C by low pressure MOCVD. [[i]]

Dimethylindium trifluoracetylacetonate InMe2(tfac) and Dimethylindium trifluoracetyl-pyvaloylmethanate InMe2 (CF3CO-CH-COtBu) are potential precursors for the CVD growth of indium-containing layers. Their ligand exchange reactions
with free diketone were studied l9F NMR in the benzene and di-isobutylketone solutions. The exchange was first order in both Me,InL and HL; the rate-controlling process
in the exchange is the rotation of one monodentate diketonate ligand about a partial double bond prior to intramolecular proton transfer to a second monodentate ligand. [[i]]
