High‐pressure fluorination (p F 2≈ 3 kbar) of Ag 2 O/Ta 2 O 3 mixtures afforded brilliant‐blue single crystals of Ag[TaF 6 ] 2 . The crystal structure is surprisingly simple: three isolated and noticeably elongated AgF 6 octahedra are each coupled cis with one another above and below the (100) plane via TaF 6 octahedra. The magnetic behavior—paramagnetism—is understandable, but F‐bridges, through which magnetic interactions could take place, are lacking.
