Abstract

UO₂F₂ abstracts F⁻ anions from TlF in liquid ammonia solution and the compound [Tl₂(NH₃)₆][{UO₂F₂(NH₃)}₂(μ-F)₂] is formed. The compound has been characterized by single crystal X-ray diffraction, Raman spectroscopy and quantum-chemical calculations for the solid state. Quantum-chemical investigation of the [{UO₂F₂(NH₃)}₂(μ-F)₂]²⁻ anion showed that the U−(μ-F)−U σ-3c-4e-bond is essentially ionic. The [Tl₂(NH₃)₆]²⁺ cation shows a thallophilic Tl⋅⋅⋅Tl interaction. Fluoride ion affinities (FIAs) were calculated for different UO₂²⁺ species [UO₂F_x]^2−x and [UO₂F_x(NH₃)_5−x]^2−x with x=0 to 4.
