Title: Synthesis and crystal structure of iron zeolitic frameworks

Abstract

Iron-based crystal structures including FeO.sub.4 tetrahedrally coordinated in three dimensions in a framework analogous to a zeolite. The structures having the general formula A.sub.yB.sub.8Fe.sub.12O.sub.24(O/OH).sub.6.xH.sub.2O in which A is Na, K, Cs, Rb or a combination thereof and B is an alkaline earth element or a combination of alkaline earth elements.
