What is #"ferrocene"#?
Ferrocene is an organometallic compound in which a
Ferrocene is (i) quite air stable, and (ii) soluble in hexanes. These are unusual properties for an iron complex, and when it appeared in the literature it caused a great deal of excitement and launched organometallic chemistry as an important field of chemistry. Geoffrey Wilkinson, and Ernst Fischer shared the Nobel Prize in 1973 for its discovery.
You will probably make some of this stuff as orange crystals as an inorganic experiment. I always thought it had a rusty iron smell, or maybe rusty iron contains ferrocene.
