Préparation et étude structurale du phosphate de fer (III) Fe(H2PO4)3

Written by sctunisie no comments

The iron phosphate Fe(H2PO4)3 cristallizes in the hexagonal system of space group R-3c. The cell parameters are: a=8.075(3) Å, c=25.606(7) Å and Z=6. The structure is built up FeO6 octahedra and PO4 tetrahedra linked by Fe-O-P bridges forming layers parallel to (-I 0 2) direction. Each layer can be described as formed by SBU-8 rings. The layers are also linked by Fe-O-P bridges forming a three dimensional framework.
