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

Abstract

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.
