What “ferrocene” means
Wiktionary · Wikipediaferrocene
- nounAny of a class of metallocenes containing an iron atom between two cyclopentadienyl rings; especially the simplest of the class bis-cyclopentadienyl iron.
Ferrocene is an organometallic compound with the formula Fe(C5H5)2. The molecule is a cyclopentadienyl complex consisting of two cyclopentadienyl rings sandwiching a central iron atom. It is an orange solid with a camphor-like odor that sublimes above room temperature, and is soluble in most organic solvents. It is remarkable for its stability: it is unaffected by air, water, or strong bases, and can be heated to 400 °C (752 °F) without decomposition. In oxidizing conditions it can reversibly re
