Treatment of UO 3 with pure triflic acid TfOH at 110 °C or with boiling triflic anhydride TfOTf afforded [UO 2 (OTf) 2 ] ( 1 ) in high yields. The latter was also prepared by the reaction of UO 3 with TfOH in water, or by dehydration of [UO 2 (OTf) 2 (H 2 O) n ] in boiling TfOTf. Anhydrous [Ce(OTf) 4 ] ( 2 ) was similarly obtained from the commercially hydrated compound. X‐ray analysis revealed that in [UO 2 (OTf) 2 (py) 3 ] ( 3 ), the triflate ligands are monodentate whereas they are dissociated in [{UO 2 (py) 4 } 2 (μ‐O)][OTf] 2 ( 4 ).
