Ferrole

In organoiron chemistry, a ferrole is a type of diiron complex containing the (OC) 3 FeC 4 R 4 heterocycle that is pi-bonded to a Fe(CO) 3 group. These compounds have Fe-Fe bonds (ca. 252 pm) and semi-bridging CO ligands (Fe-C distances = 178, 251 pm). They are typically air-stable, soluble in nonpolar solvents, and red-orange in color.
