A new thio­phosphate, Rb_0.38Ag_0.5Nb₂PS₁₀

The structure of the new pentanary thio­phosphate, Rb_0.38Ag_0.5Nb₂PS₁₀, is made up of one-dimensional [Nb₂PS] chains, which are stabilized by Ag⁺ and disordered Rb⁺ ions.

Magnesium aluminium chromite

The structure of a natural magnesium aluminium chromite spinel was investigated. The best refined cation distribution is (Mg,Al,Fe)[Al,Cr,Fe,Φ]O.

High-pressure syntheses of α-RE₂B₄O₉ (RE = Sm, Ho), with a structure type displaying edge-sharing BO₄ tetrahedra

The title compounds were obtained by the reaction of RE₂O₃ (RE = Sm and Ho) and B₂O₃ under high-pressure/high-temperature conditions of 7.5–10 GPa and 1323 K using Walker-type multianvil assemblies.

Synthesis and ab initio X-ray powder diffraction structure of the new alkali and alkali earth metal borate NaCa(BO₃)

The fundamental building unit of the title compound, sodium calcium orthoborate, is the isolated planar BO₃ group. The Ca²⁺ and Na⁺ cations share the O atoms with the BO₃ groups to form distorted coordination polyhedra. Mixed occupancy exists in the Ca sites.

Al₆Ti₂O₁₃, a new phase in the Al₂O₃–TiO₂ system

The existence of Al₂O₃–TiO₂ phases with an Al to Ti ratio greater than 2 has previously been suggested by transmission electron microscopy. However, the present Al₆Ti₂O₁₃ structure is the first determination of such a compound. The chain-like structure is formed by oxygen octa­hedra and trigonal bipyramids, the latter solely occupied by Al and the former by both Al and Ti. It should be noted that the fivefold coordination around Al is slightly unusual.
