Abstract

The new orthorhombic Fe(AsO₄) phase has been synthesized by thermal treatment at 525 °C of a new (NH₄)[Fe(AsO₄)F] compound, with a [Fe(AsO₄)F]⁻ skeleton showing channels where the ammonium cations are located. The crystal structure of Fe(AsO₄) has been solved from single-crystal data. The structure is formed by layers of edge-sharing dimeric octahedra, and interconnected by chains of alternating FeO₆ octahedra and AsO₄ tetrahedra.
