The effect of encapsulated cyanide complexes on the localization of cations in faujasite

Features of the localization of various types of cations and their distribution between the structural elements of the framework of faujasite with encapsulated hexacyanide complexes of iron(II) and cobalt(III) were established. The content of the alkali-metal cations in the sodalite cells is increased compared with faujasite, and the cations of the transition metals are localized in the large cavities with the formation of Me(S_II)−NC−Fe(CN)₅ (Me=Cu, Co) and (NC)₅Fe−CN−Me(S_V)−NC−Fe(CN)₅ (Me=Ni, Cu, Co) fragments.
