摘要：
The terminal actinide fluoride bonds in (C5Me5)(2)ThF2(py) (py = pyridine) and (C5Me5)(2)UF2(O = PR3) (R = Me, Ph) react with two equivalents of Me3SiN3 in toluene to form the polymeric thorium bis(azide), [(C5Me5)(2)Th(N-3)(2)](infinity), and a new class of monometallic uranium bis(azide) complexes, (C5Me5)(2)U(N-3) (2)(O = PR3), respectively. Full characterization of the novel complexes (C5Me5)(2)ThF2(py) and (C5Me5)(2)UF2(O = PR3) are reported, including the solid-state structures of (C5Me5)(2)ThF2(py) and (C5Me5)(2)U(N-3)(2)(O = PPh3). Electronic absorption spectral data are also reported for (C5Me5)(2)AnF(2)(py) (An = Th, U) and (C5Me5)(2)U(N-3)(2)(O = PR3) to confirm metal oxidation state and enable elucidation of the fluoride and azide ligand bonding in these complexes.
