Cerocene is a organometallic complex with the chemical formula Ce(C8H8)2. [1] [2] It is a sandwich compound containing a central cerium atom and two cyclooctatetraenide rings.
Cerocene can be prepared by reducing cerium(III) di-cyclooctatraene anion salts.
Cerocene decomposes when exposed to water or oxygen to yield non-stoichiometric cerium-oxides and cyclooctratraene derivitives. [2]
It undergoes a disproportionation, leading to an equilibrium between cerocene and a double-decker structure containing two cerium atoms: [2]
Cerocene is a known precursor for uranocene, U(C8H8)2. [1]
Ce(C8H8)2 + UCl3⇌ U(C8H8)2
Cerocene is commonly confused with the compound tris(cyclopentadienyl)cerium.
