摘要: Abstract The hexafluoroacetylacetonate (hfac) chemistry of lead was investigated to make comparisons with the similarly sized lanthanides that form air stable Ln(hfac)3(diglyme) complexes. [Pb(hfac)2(μ-η3:η1-diglyme)]2 obtained from PbO, (MeOCH2CH2)2O, and H(hfac) found exist in solid state as chiral pairs linked via diglyme. metal is eight coordinate, but has sufficient vacant space coordination sphere be considered have an hemi-directed environment. In contrast Ln(hfac)3(digyme)/K reactions generate [LnF(hfac)3K(diglyme)]2 fluoride complexes, potassium reduction complex gave only [(18-crown-6)K(hfac)]n pure form, a displays bridging CF3 linkages state.
