Chemical compound
Platinum(II) bis(acetylacetonate) is the coordination compound with the formula Pt(O2 C5 H7 )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(H2 O)4 ]2+ with acetylacetone .[ 4]
