Uranosena

Uranocene, U(C₈H₈)₂, adalah senyawa organouranium yang tersusun dari atom uranium yang diapit diantara dua cincin siklooktatetraenida. Senyawa tersebut adalah salah satu senyawa organoaktinida pertama yang disintesis. Senyawa tersebut adalah padatan hijau yang sensitif terhadap udara yang larut dalam pelarut organik. Uranosena, salah satu anggota dari "aktinosena," sekelompok metalosena yang menggabungkan unsur-unsur dari rangkaian aktinida.^[1]^[2]^[3]^[4]^[5]^[6]^[7]^[8]^[9]^[10]^[11]^[12]
