Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>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, [CeO(L_OEt)₂(H₂O)]⋅MeC(O)NH₂ (<bold>1</bold>; L_OEt⁻=[Co(η⁵‐C₅H₅){P(O)(OEt)₂}₃]⁻), featuring a short CeO bond (1.857(3) Å). DFT calculations indicate that the hydrogen bond to cocrystallized acetamide plays a key role in stabilizing the CeO moiety of <bold>1</bold> in the solid state. Complex <bold>1</bold> exhibits oxidizing and nucleophilic reactivity.</p> </abstract>
