    The uranium(IV) triflate [U(OTf)4] (1) (OTf = OSO2CF3) gives stable adducts with Lewis bases, such as [U(OTf)4(py)] (2) (py = pyridine). The crystal structure of a solvate of [U(OTf)4(OPPh3)3] (3), which exhibits a bidentate OTf group, has been determined. Substitution of the triflate ligands of 1 with LiNEt2, Kacac (acac = MeCOCHCOMe), KCp (Cp = η-C5H5), and K2COT (COT = η-C8H8) has led to the formation
