| Abstract: | 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(LOEt)2(H2O)]?MeC(O)NH2 ( 1 ; LOEt?=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 1 in the solid state. Complex 1 exhibits oxidizing and nucleophilic reactivity. |
