Potassium salts of hypodi­phospho­ric acid

Structural analysis of six potassium salts of hypodiphospho­ric acid, H₄P₂O₆, containing the anions in all possible basicities, is focused on the anion structure and the organization of the anionic and cationic sublattices.

Fe_6.67(PO₄)_5.35(HPO₄)_0.65 and Fe_6.23(PO₄)_4.45(HPO₄)_1.55: two new mixed-valence iron phosphates

Two new mixed-valence iron phosphates, with crystal structures similar to that of the well known synthetic compound Fe₇(PO₄)₆, have been synthesized hydro­thermally at 973 K and 0.1 GPa. The structures are characterized by edge-sharing Fe polyhedra forming chains parallel to the [101] direction. These chains are connected together by Fe3 octa­hedra and PO₄ tetra­hedra. Fe^III is located in the Fe1 and Fe2 octa­hedra. Fe3 occurs in a five-coordinated environment and is occupied by Fe^II, whereas the Fe4 octa­hedra are occupied by Fe^II and vacancies.

Ba_1.01Sr_0.99P₂O₇: un nouveau site Ba²⁺ révélé par diffraction des rayons X

The divalent cations in Ba_1.01Sr_0.99P₂O₇ are distributed on three different sites with non-unit occupancies, in contrast with isostructural compounds where only two sites are fully occupied.
