文摘

Electrochemical reduction/oxidation cycles of immobilised powder mixtures of KCu[hcc] and KZn[hcf] as well as their mechanical milling lead to the formation of a quaternary solid solution (mixed crystals) with Cu2+ and Zn2+ on the nitrogen coordinated sites and Fe3+ and Co3+ on the carbon coordinated sites. The reaction products were studied by the X-ray diffractometry and voltammetric techniques. The formation of solid solutions of the general formula KCu_xZn_1-x[hcc]_x[hcf]_1-x is the first example of an electrochemical and mechanochemical reaction leading to mixed hexacyanometalates.
