用三甲基氮氧化物直接氧化三胺胺铀(III)得到了铀(V)末端的单氧络合物，这是铀(V)单分子磁体(SMM)的第一个明确例子。这种单金属络合物明确地表明，可以使用强轴向连接的各向异性配位场来克服铀(V)的有限磁各向异性。(版权所有2013 Wiley-VCH Verlag GmbH and Co.KGaA，Weinheim)
Straightforward oxidation of a triamidoamine uranium(III) complex with trimethyl-N-oxide affords a uranium(V) terminal mono-oxo complex which is the first clear-cut example of a uranium(V) single-molecule magnet (SMM). This monometallic complex unambiguously shows that a strongly axially ligated and thus anisotropic ligand field can be used to overcome the limited magnetic anisotropy of uranium(V).
