摘要

本文报道了含单核[RuF6]−、双核[Ru2F11]−和三核[Ru3F16]−阴离子Rb[RuF6]、Cs[Ru2F11]和[O2][Ru3F16]的合成，并通过单晶x射线衍射对其进行了表征。这种三核阴离子首次被描述为Ru。用拉曼光谱研究Rb[RuF6]，用红外光谱和拉曼光谱研究Cs[Ru2F11]。通过量子化学计算研究了RuF5和Ru2F10、Ru3F15的氟离子亲和性，结果表明，与SbxF5⋅x相比，Ru2F10和Ru3F15的氟离子亲和性随核度的增加而降低。固有键轨道计算表明，阴离子[Ru2F11]−和[Ru3F16]−中的μ-F−Ru键本质上是离子键。

Mono-, Di-, and Trinuclear Complex Anions of RuF5 in Rb[RuF6], Cs[Ru2F11], and [O2][Ru3F16]

Herein, we report the synthesis of Rb[RuF₆], Cs[Ru₂F₁₁], and [O₂][Ru₃F₁₆] containing mononuclear [RuF₆]⁻, dinuclear [Ru₂F₁₁]⁻, and trinuclear [Ru₃F₁₆]⁻ anions, respectively, and their characterization by single-crystal X-ray diffraction. Such a trinuclear anion is described for Ru for the first time. Rb[RuF₆] was additionally investigated by Raman spectroscopy while Cs[Ru₂F₁₁] was studied by IR and Raman spectroscopy. The fluoride ion affinities of RuF₅ and the hypothetic molecules Ru₂F₁₀ and Ru₃F₁₅ were studied by quantum-chemical calculations and shown to decrease with increasing nuclearity in contrast to Sb_xF_5 ⋅ x species. Intrinsic bond orbital calculations show essentially ionic μ-F−Ru bonds in the anions [Ru₂F₁₁]⁻ and [Ru₃F₁₆]⁻.
