Actinocenes are a family of organoactinide compounds consisting of metallocenes containing elements from the actinide series. They typically have a sandwich structure with two dianionic cyclooctatetraenyl ligands (COT2−, which is C

) bound to an actinide-metal center (An) in the oxidation state IV, resulting in the general formula An(C8H8)2.
