The iron phosphate NaZnFe₂(PO₄)₃

M. Hidouri, B. Lajmi and M. Ben Amara

Synopsis: NaZnFe₂(PO₄)₃ features a new structural type built up from ZnO₆ octahedra, FeO₆ octahedra and FeO₄ tetrahedra, linked together via the corners and edges of PO₄ tetrahedra to form a three-dimensional framework, with tunnels running along [100]. Within these tunnels, Na⁺ cations occupy highly distorted cubic sites.

Formula: NaZnFe₂(PO₄)₃
