This interest is stimulated jointly by scientific curiosity of a relatively unexplored field and the myriad applications that these elements have found in diverse areas such as organic synthesis, materials science and nuclear fuel cycles. 1 Our research focuses on stabilising f -element complexes with unusual coordination geometries and/or oxidation states , which can provide enhanc ed reactivity and unique physical properties. 1 We mainly utilise bulky bis(silyl)amides and cyclopentadienyls as supporting ligands to stabilise these unusual f -element motifs. H ere we will present some recent h ighlights of this work , such as the first nea r-linear f -element complexes ( 1),2 the first measurements of actinide covalency by pulsed EPR spectroscopy on the Th(III) complex (2)3 and the first isolated f -block metallocenium cations ( 3), which provided record magnetic hysteresis temperatures for the dysprosium analogue in 2017 .4 (1) (2) (3)
