(contracted; show full)|2|+}} originally called ferricinium, but now more commonly ferrocenium (these terms denote the ''same'' ion, contrary to what one would expect from the fact that [[ferric]] and [[ferrous]] denote different ions of a single iron atom).  On a preparative scale, the oxidation is conveniently effected with FeCl<sub>3</sub>, to give the ion, which is often isolated as its [[hexafluorophosphate|{{chem|PF|6|−}}]] salt. Alternatively, [[silver nitrate]] may be used as the oxidizer.

Ferrocenium salts are sometimes used as oxidizing agents, in part because the product ferrocene is fairly inert and readily separated from ionic products.<ref>{{cite journal|first1=N.
