A recent ruthenium-free Gratzl cell developed by Daeneke et al used this ion and its cation as the couple in place of the typical iodide/tri-iodide couple. While a cyanide compound is used in current second-generation glucometers, the original design relied upon the interaction between glucose oxidase and a derivative of this molecule.

A recent ruthenium-free Gratzl cell developed by Daeneke et al used this ion and its cation as the couple in place of the typical iodide/tri-iodide couple. While a cyanide compound is used in current second-generation glucometers, the original design relied upon the interaction between glucose oxidase and a derivative of this molecule. Keally, Pauson, and Miller published an incorrect "sigma" structure of this molecule, while Sidgwick's rule was used to determine its correct pi structure by Woodward and Wilkinson. A common lab procedure for the Bronsted-Lowry-acid-catalyzed Friedel-Crafts acetylation of this compound relies on column chromatography to separate its orange monoacetylated form from its reddish diacetylated form. This superaromatic compound is a stronger nucleophile than benzene because six pi electrons are distributed over five carbon atoms on each of the two rings that form its sandwich structure. For 10 points, name this compound consisting of two cyclopentadienyl rings and an iron atom.
