Gallium acetylacetonate, also referred to as Ga(acac)3, is a coordination complex with formula Ga(C5H7O2)3. This gallium complex with three acetylacetonate ligands is used in research. The molecule has D3 symmetry, being isomorphous with other octahedral tris(acetylacetonate)s.[1]

Uses

Gallium oxide thin films can be produced by atomic layer epitaxy (ALE) by combining gallium acetylacetonate with either water or ozone as the precursor.[2] Ga(acac)3 can also be used for low temperature growth of high purity gallium nitride nano-wires and nano-needles.[3][4]
