Reaction of the Ruddlesden-Popper phases Sr2Fe0.5Ru0.5O4 and Sr-3(Fe0.5Ru0.5)(2)O-7 with CaH2 results in the topochemical deintercalation of oxide ions from these materials and the formation of samples with average compositions of Sr2Fe0.5Ru0.5O3.35 and Sr-3(Fe0.5Ru0.5)(2)O-5.68, respectively. Diffraction data reveal that both the n = 1 and n = 2 samples consist of two-phase mixtures of reduced phases with subtly different oxygen contents. The separation of samples into two phases upon reduction is discussed on the basis of a short-range inhomogeneous distribution of iron and ruthenium in the starting materials. X-ray absorption data and Mossbauer spectra reveal the reduced samples contain an Fe3+ and Ru2+/3+ oxidation state combination, which is unexpected considering the Fe3+/Fe2+ and Ru3+/Ru2+ redox potentials, suggesting that the local coordination geometry of the transition metal sites helps to stabilize the Ru2+ centers. Fitted Mossbauer spectra of both the n = 1 and n = 2 samples are consistent with the presence of Fe3+ cations in square planar coordination sites. Magnetization data of both materials are consistent with spin glass-like behavior.
