The triple pyrophosphate Cs₃CaFe(P₂O₇)₂

The title compound, Cs₃CaFe(P₂O₇)₂, consists of [FeO₅] and [CaO₆] polyhedra inter­connected by two types of P₂O₇ groups. Cs atoms are located in three positions inside channels which run along a.

Substitutional and positional disorder in Sr_2.88Cu_3.12(PO₄)₄

In Sr_2.88Cu_3.12(PO₄)₄, the special Sr1 site (2b, site symmetry ) is occupied by 0.88 (3) Sr and 0.12 (3) Cu, while Sr2 cations partially occupy two positions denoted as Sr2a and Sr2b, separated by a distance of 0.48 (3) Å. The Sr cations are situated between layers formed by the connection of Cu atoms by PO₄ tetra­hedra.
