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.[2] The compound is a widely used precursor to platinum-based catalysts.[3]

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

The complex is prepared by the reaction of the platinum(II) aquo complex [Pt(H2O)4]2+ with acetylacetone.[4]
