Abstract

The europium hexafluoroacetylacetonate complex Eu(hfac)₃(diglyme) was synthesized to examine its fluorescence and conversion to a Eu(II) analog. Reaction of Eu(hfac)₃(diglyme) with potassium produced the unexpected trivalent product [EuF(hfac)₃K(diglyme)]₂. This reduction system was studied further by synthesizing other Ln(hfac)₃(diglyme) analogs and examining their reactivity with potassium. The Nd, Sm, and Gd analogs of Ln(hfac)₃(diglyme) also react with potassium to form [LnF(hfac)₃K(diglyme)]₂ as observed for europium. Reactions of the Eu(II) precursors, EuI₂(thf)₄ and {[Zr₂(OⁱPr)₉]Eu(μ-I)}₂ with K(hfac) also form trivalent products, namely Eu(hfac)₃(diglyme) and [Zr₂(OⁱPr)₉]Eu(hfac)₂.
