Chemical compound

Platinum(II) bis(acetylacetonate) is the coordination compound with the formula Pt(O₂C₅H₇)₂, abbreviated Pt(acac)₂. The homoleptic acetylacetonate complex of platinum(II), it is a yellow, benzene-soluble solid. According to X-ray crystallography, the Pt center is square planar. The compound is a widely used precursor to platinum-based catalysts.

Packing of Pt(acac)₂ molecules within a crystal.

The complex is prepared by the reaction of the platinum(II) aquo complex with acetylacetone.
