Metal β-diketone complexes. Part VII. Some reactions of the acid complexes HPt(acac)2X (X = Cl or Br)

The reactions of the acid complexes HPt(acac)2X (X = Cl or Br) with a range of mono- and bi-dentate ligands have been investigated. Three main types of complex have been isolated: PtX(acac)L, containing an O-bonded acetylacetone (acac) and a monodenate ligand (L), PtCl(acac)L′ containg a C-bonded acetylacetone and a bidentate ligand L′, and Pt2Cl2(acac)2(diolefin) containing bridging diolefins. The i.r. spectra (400–4000 cm.–1) are reported and are consistent with the suggested structures. Mass spectra and n.m.r. spectra are also reported where appropriate and are discussed in terms of the suggested structures.
