The first oxyfluorinated iron(II, III) phosphate (Fe3+Fe2+F2 (HPO4)2(H2O)2, ethylenediamine] with an open structure has been synthesized. It is triclinic (P-1 (No. 2), a = 5.174(2) Å, b = 7.518(2) Å, c = 8.773(3) Å, α = 108.37(1)°, β = 97.33(2)°, γ = 109.86(2)°, Z = 1). Its bidimensional structure contains chains of Fe(II) and Fe(III) octahedra, arranged in an ordered way and linked to each other by phosphate groups.
