Title: Synthesis of a ferrolite: A zeolitic all-iron framework

Abstract

Here, crystals of the first sodalite-type zeolite containing an all-iron framework, a ferrolite, Ba 8(Fe 12O 24)Na y(OH)6 • xH 2O, were synthesized using the hydroflux method in nearly quantitative yield. Ba 8(Fe 12O 24)Na y(OH) 6 • xH 2O crystallizes in the cubic space group Pm3¯m with α = 10.0476(1) Å. Slightly distorted FeO 4 tetrahedra are linked to form Fe 4O 4 and Fe 6O 6 rings, which in turn yield channels and internal cavities that are characteristic of the sodalite structure. Barium, sodium, and hydroxide ions and water molecules are found in the channels and provide charge balance. Magnetic measurements indicate that the ferrolite exhibits magnetic order up to at least 700 K, with the field-cooled and zero-field-cooled curves diverging. Analysis of the 57Fe Mossbauer spectra revealed two spectral components that have equal spectral areas, indicating the presence of two subsets of iron centers in the structure. Dehydrated versions of the ferrolite were also prepared by heating the sample.
