Chemistry:Stannocene

From HandWiki

Stannocene is an organometallic compound with the formula Sn(C
5
H
5
)
2
. It appears yellow-brown, and melts around 105 °C.[1]

Chemically, stannocene is a metallocene that can be produced efficiently from cyclopentadienyl sodium and tin(II) chloride.[2] Unlike in ferrocene the two cyclopentadienyl rings are not parallel.[3]

Stannocene reacts with strong Lewis acids to give the cyclopentadienyltin(II) cation, SnC5H+5.[4]
