A novel In₃O₁₆ fragment in Cs₃In₃(PO₄)₄

Tricaesium triindium tetra­phosphate, Cs₃In₃(PO₄)₄, features a three-dimensional structure composed of an In₃O₁₆ fragment of corner-sharing InO₆ polyhedra inter­linked by PO₄ groups into an anionic network, providing tunnels along c where two distinct Cs⁺ cations reside. The structure is closely related to that of K₃In₃(PO₄)₄, with the main difference being in the geometry of the In₃O₁₆ fragments due to the different coordination requirements of Cs and K.

Cs₆Nb₄Se₂₂ and K₁₂Nb₆Se_35.3: two new compounds containing the M₄Q₂₂ building block

Cs₆Nb₄Se₂₂ contains two Nb₂Se₁₁ building blocks linked by an Se—Se bond to form isolated Nb₄Se₂₂ tetra­meric building blocks surrounded by caesium ions. K₁₂Nb₆Se_35.3 contains similar Nb₄Se₂₂ tetra­mers that are linked by an Se—Se—Se unit to an Nb₂Se₁₁ dimer to form one-dimensional anionic chains surrounded by potassium ions.

(NH₄)₂WTe₂O₈ at 5.09 GPa: a single-crystal study using synchrotron radiation

The crystal structure of (NH₄)₂WTe₂O₈ was determined at 5.09 GPa using single-crystal X-ray diffraction in a diamond-anvil cell. No phase transition was observed up to 7.16 GPa. However, a full structure determination at 5.09 GPa shows that the coordination number of one of the two non-equivalent Te atoms has decreased from four to three.
