A Structurally Characterized Organometallic Plutonium(IV) Complex
Abstract
The blood‑red plutonocene complex Pu(1,3‑COT′′)(1,4‑COT′′) (4; COT′′=η8‑bis(trimethylsilyl)cyclooctatetraenyl) has been synthesized by oxidation of the anionic sandwich complex Li[Pu(1,4‑COT′′)2] (3) with anhydrous cobalt(II) chloride. The first crystal structure determination of an organoplutonium(IV) complex revealed an asymmetric sandwich structure for 4 where one COT′′ ring is 1,3‑substituted while the other retains the original 1,4‑substitution pattern. The electronic structure of 4 has been elucidated by a computational study, revealing a probable cause for the unexpected silyl group migration.
