Web2.3 Mineral Groups. Most minerals are made up of a cation (a positively charged ion) or several cations, plus an anion (a negatively charged ion (e.g., S 2− )) or an anion complex (e.g., SO 42−). For example, in the mineral hematite (Fe 2 O 3 ), the cation is Fe 3+ (iron) and the anion is O 2− (oxygen). The two Fe 3+ ions have an overall ... WebFe–S clusters can be classified according to their Fe:S stoichiometry [2Fe–2S], [4Fe–3S], [3Fe–4S], and [4Fe–4S]. [6] The [4Fe–4S] clusters occur in two forms: normal ferredoxins and high potential iron proteins (HiPIP). Both adopt cuboidal structures, but they utilize different oxidation states. They are found in all forms of life. [7]
