Green rust

Green rust is a generic name for various green crystalline chemical compounds containing iron(II) and iron(III) cations, the hydroxide (HO−) anion, and another anion such as carbonate (CO2−3), chloride (Cl−), or sulfate (SO2−4), in a layered double hydroxide structure. The most studied varieties are * carbonate green rust - GR(CO2−3): [Fe2+4Fe3+2(HO−)12]2+ · [CO2−3·2H2O]2−. * chloride green rust - GR(Cl−): [Fe2+3Fe3+(HO−)8]+ · [Cl−·nH2O]−. * sulfate green rust - GR(SO2−4): [Fe2+4Fe3+2(HO−)12]2+ · [SO2−4·2H2O]2−.
