Comproportionation of the platinum(0) complex Pt(PMe3)4 with the platinum(II) hexafluoroacetylacetonate complexes Pt(hfac)2 or [Pt(hfac)(PMe3)2][hfac] yields diplatinum species of stoichiometry [Pt2(μ-hfac)(PMe3)4][hfac], 1, and [Pt2(PMe3)6][hfac]2, 2, respectively. The NMR spectra and X-ray crystal structure of 1 show that the two platinum centers are chemically inequivalent; one is a square-p...
