Whereas terminal oxo complexes of transition and actinide elements are well documented, analogous lanthanide complexes have not been reported to date. Herein, we report the synthesis and structure of a cerium(IV) oxo complex, [CeO(L OEt ) 2 (H 2 O)]⋅MeC(O)NH 2 ( 1 ; L OEt − =[Co(η 5 ‐C 5 H 5 ){P(O)(OEt) 2 } 3 ] − ), featuring a short CeO bond (1.857(3) Å). DFT calculations indicate that the hydrogen bond to cocrystallized acetamide plays a key role in stabilizing the CeO moiety of 1 in the solid state. Complex 1 exhibits oxidizing and nucleophilic reactivity.
