Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Potassium hexafluoridotechnetate(IV), K₂[TcF₆], slowly reacts in aqueous solution with acetohydroxamic acid with formation of the ammine nitrosyltechnetium(I) complex [Tc(NO)(NH₃)₄F]⁺. The product crystallizes as mixed TcF₆^2–/HF₂^– salt of the composition [Tc(NO)(NH₃)₄F]₄[TcF₆][HF₂]₂. [Tc(NO)(NH₃)₄F]⁺ represents the first nitrosyltechnetium complex with a fluorido ligand in its coordination sphere. The Tc–F bonds in two crystallographically independent species are 1.987(2) and 2.034(2) Å, respectively. This is slightly longer than in the [TcF₆]^2– counterion.</p> </abstract>
