Plumbocene is an organometallic compound of lead with the chemical formula Pb(C5H5)2. It is a member of the class of metallocenes. It is soluble in benzene, acetone, ether, and petroleum ether, and insoluble in water. Plumbocene is stable in cold water.[1]

Plumbocene is not commercially available. It may be synthesized by the reaction of sodium cyclopentadienide with a lead(II) source such as lead(II) nitrate[1] or lead(II) iodide.[2]

The decamethyl analog, PbCp*2 (decamethylplumbocene), and the half-sandwich complexes, Cp*Pb[BF4] (lead(II) pentamethylcyclopentadienide tetrafluoroborate) and Cp*PbCl (lead(II) chloride pentamethylcyclopentadienide), are known as well.[3]
