A Structurally Characterized Organometallic Plutonium(IV) Complex

Abstract

The blood-red plutonocene complex Pu(1,3-COT `')(1,4-COT `') (4; COT `' = eta(8)-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.
