Strontium magnesium phosphate, Sr_2+xMg_3−xP₄O₁₅ (x ∼ 0.36), from laboratory X-ray powder data

The previously unknown crystal structure of Sr_2.36Mg_2.64P₄O₁₅, which was thought to be stoichiometric Sr₂Mg₃P₄O₁₅, has been determined and refined from laboratory powder X-ray diffraction data, representing a new structure type.

CsAlZr₂(PO₄)₄: an anhydrous aluminium zirconium phosphate with a novel three-dimensional framework

This represents the first detailed structural analysis of an anhydrous phosphate containing both zirconium and aluminium. The structure features a complicated three-dimensional framework of [AlZr₂(PO₄)₄] constructed by PO₄, AlO₄ and ZrO₆ polyhedra inter­connected via corner-sharing O atoms, and one-dimensional Cs chains which are located in the infinite tunnels within the [AlZr₂(PO₄)₄] framework, which run along the c axis.
