摘要: Potassium hexafluoridotechnetate(IV), K2[TcF6], slowly reacts in aqueous solution with acetohydroxamic acid formation of the ammine nitrosyltechnetium(I) complex [Tc(NO)(NH3)4F]+. The product crystallizes as mixed TcF62–/HF2– salt composition [Tc(NO)(NH3)4F]4[TcF6][HF2]2. [Tc(NO)(NH3)4F]+ represents first nitrosyltechnetium a fluorido ligand its coordination sphere. Tc–F bonds two crystallographically independent species are 1.987(2) and 2.034(2) A, respectively. This is slightly longer than [TcF6]2– counterion.
