The Mixed Anionic Framework in the Structure of Na₂{MnF[PO₄]}

O. V. Yakubovich, O. V. Karimova and O. K. Mel'nikov

In the crystal structure of hydrothermally synthesized sodium manganese fluoride orthophosphate, Na₂{MnF[PO₄]}, two kind of cis-MnO₄F₂ octahedra share common vertices to form (Mn₂F₂O₈) chains parallel to the b axis of the monoclinic unit cell. In the a and c directions these chains are linked by PO₄ tetrahedra to form a three-dimensional framework of octahedra and tetrahedra. Na⁺ cations are located in the channels of this framework structure. The problem of {OTX₅} mixed anionic radical polymorphism is discussed.
