Plutonocene, Pu(C8H8)2, is an organoplutonium compound composed of a plutonium atom sandwiched between two cyclooctatetraenide (COT2-) rings. It is a dark red, very air-sensitive solid that is sparingly soluble in toluene and chlorocarbons.[1][2] Plutonocene is a member of the actinocene family of metallocenes incorporating actinide elements in the +4 oxidation state.
Compared to other actinocenes such as uranocene, plutonocene has been studied to a lesser degree since the 1980s due to the notable radiation hazard posed by the compound.[3][4] Instead, it has mostly been the subject of theoretical studies relating to the bonding in the molecule.[4][5]
