Two new iron(III) arsenates K(2)Fe(2)O(AsO(4))(2) (1) and Rb(2)Fe(2)O(AsO(4))(2) (2) have been synthesized and characterized by single-crystal X-ray diffraction, magnetic susceptibilities, and Mossbauer spectroscopy. The two compounds are isostructural and exhibit a sheet structure consisting of infinite slabs of edge-sharing FeO(6)
