The high-yield synthesis, spectroscopic and structural determination of three new uranium(IV) and thorium(IV) “ate” complexes supported by three different diamido ether ligands are reported. The reaction of Li2[2,6-iPr2PhN(CH2CH2)]2O (Li2[DIPPNCOCN]) with 1 equiv. of UCl4 in THF generates [DIPPNCOCN]UCl3Li(THF)2 (1), while reaction in toluene/ether gives salt-free [DIPPNCOCN]UCl2·½C7H8 (2), which was
