Iron is the first of the transition metals that cannot reach its group oxidation state of +8, although its heavier congeners ruthenium and osmium can, with ruthenium having more difficulty than osmium. Ruthenium exhibits an aqueous cationic chemistry in its low oxidation states similar to that of

Among the halide and pseudohalide complexes, fluoro complexes of iron(III) are the most stable, with the colorless being the most stable in aqueous solution. Chloro complexes are less stable and favor tetrahedral coordination as in ; and are reduced easily to iron(II).
