A type of chemical compound made of iron sandwiched between two cyclopentadienyl rings, known for its stability and use in various chemical applications.
Ferrocene is often used in research for its unique properties as a metallocene.
Ferrocene is formed from "ferro-" (from Latin "ferrum", meaning iron) and "-cene" (from Greek "kainos", meaning new). The word refers to a new class of compounds containing iron, specifically metallocenes, which are characterized by their sandwich-like structure with iron between two cyclopentadienyl anions.
Think of 'iron' ('ferro-') being part of a 'new' class of compounds ('-cene') — that's why ferrocene is a new type of iron compound.
