Wikipedia
Chromocene
Chromocene is the organochromium compound with the formula [Cr(C5H5)2]. Like structurally related metallocenes, chromocene readily sublimes in a vacuum and is soluble in non-polar organic solvents. It is more formally known as bis(η5-cyclopentadienyl)chromium(II).

Chromocene
Chromocene, formally known as bischromium, is a chemical compound with the condensed structural formula [Cr(C5H5)2]. Each molecule contains an atom of chromium bound between two planar systems of five carbon atoms known as cyclopentadienyl rings in a sandwich arrangement, which is the reason its formula is often abbreviated as Cp2Cr. It is an organometallic compound as it has covalent chromium–carbon bonds. Chromocene is structurally similar to ferrocene, the prototype for the metallocene class of compounds; however, as it has only 16 valence electrons, it does not follow the 18-electron rule. It is a paramagnetic compound and also highly reducing, both consequences of its low valence electron count. Like structurally related metallocenes, chromocene readily sublimes in a vacuum and is soluble in non-polar organic solvents. Ernst Otto Fischer, who shared the 1973 Nobel Prize in Chemistry for his work on sandwich compounds, was the first to report a synthesis for chromocene. One simple method of preparation involves the reaction of chromium chloride with sodium cyclopentadienide: Such syntheses are typically conducted in THF; decamethylchromocene, Cr[C5(CH3)5]2, can be prepared analogously from LiC5(CH3)5. Chromocene can also be prepared from chromium chloride in a redox process:
