reactions of PtCl2 or K2PtCl6 (at about 240 °C). Excess diketonate salt plays the role of a reducing agent in the conversion of Pt (IV) salt to Pt (II) compounds. The effect of grinding on properties of the ground mixtures was studied by XRD, IR, and thermal analysis methods. The difference in the course of the interaction of PtCl4 with Na(hfac) or Na(tfac) indicates the dependence of the reaction on
Five-coordinate Bis(1,1,1,5,5,5-hexafluoro-2,4-pentanedionato)(tertiary phosphine)palladium(II) and -platinum(II) Complexes. X-Ray Crystal and Molecular Structures and Fluxional Motions in Solution
and structures of [Pd(hfac)2P(o-tolyl)3}] and [Pt(hfac)2P(cyclohexyl)3}] were determined by X-ray analysis. Both complexes have very distorted square-pyramidal structures, one of the two hfac anions in either of them spanning the apical and basal coordination sites. NMR spectra at various temperatures disclosed the fluxional behaviors of these complexes which retain the solid-state structures at such
