We synthesized a silver iron oxyfluoride AgFeOF2 by using a high-pressure reaction. Synchrotron X-ray and neutron diffraction, X-ray absorption, and 57Fe Mössbauer spectroscopy indicate that AgFeOF2 crystallizes in the ideal perovskite structure with iron in a trivalent state, although electron microscopy revealed weak super-reflections. A possible partial ordering in the FeO2F4 octahedron is inferred from Mössbauer spectroscopy. The synthesis of the fluorine-rich sample offers an opportunity to study a composition-property relation in AFeIIIO3–nFn (n = 0, 1, and 2). AgFeOF2 exhibits a G-type antiferromagnetic ordering below TN ≈ 480 K, which is much lower than the n = 0 and 1 cases, suggesting a weaker superexchange interaction between Fe moments via F 2p orbitals (vs O 2p orbitals).

AgFeOF 2：富氟钙钛矿型氟氧化物
我们通过高压反应合成了氟氧化银铁AgFeOF 2。同步加速器的X射线和中子衍射，X射线吸收以及57 FeMössbauer光谱表明，AgFeOF 2以理想的钙钛矿结构结晶，铁处于三价态，尽管电子显微镜显示微弱的超反射。从穆斯堡尔光谱法推断出FeO 2 F 4八面体中可能的部分有序。富氟样品的合成为研究A Fe III O 3– n F n（n= 0、1和2）。AgFeOF 2所呈现ģ型反铁磁性有序下面Ť Ñ ≈480 K，其远远超过了降低Ñ = 0和1的情况下，表明铁的时刻之间经由˚F2p轨道较弱的超交换相互作用的（VSö2p轨道）。
