Rb₅Mo₂₇Se₃₁, a novel ternary reduced molybdenum selenide containing Mo₁₂ and Mo₁₅ clusters

The structure of Rb₅Mo₂₇Se₃₁ consists of both Mo₁₂Se₁₄Se₆ and Mo₁₅Se₁₇Se₆ clusters, connected through inter-cluster Mo—Se bonds. Rb⁺ cations occupy large voids between the different clusters.

Hexagonal high-temperature form of aluminium phosphate tridymite from X-ray powder data

Rietveld refinement shows that above 573 K, AlPO₄ tridymite has a dynamically disordered tetrahedral framework structure with an ordered cation distribution. The average structure, with strongly anisotropic displacement parameters for oxy­gen, and the split-atom model explain the diffraction pattern equally well.

Lu₂SiO₅ by single-crystal X-ray and neutron diffraction

The structure of the well known scintillator material Lu₂SiO₅ (LSO), which is used for γ detection in medical imaging and high-energy physics, has been determined from neutron diffraction data. It consists of isolated ionic SiO₄ tetrahedral units and non-Si-bonded O atoms in distorted OLu₄ tetrahedra. The OLu₄ tetrahedra form edge-sharing infinite chains and double O₂Lu₆ tetrahedra along the c axis.

Chromous hydrazine sulfate

Chromous hydrazine sulfate at 100 K is similar to its zinc analogue, with chains of chromium(II) ions linked by sulfate anions and extensive hydrogen bonding between the H atoms of the coordinated hydrazinium ligands and O atoms of the sulfate anions which bridge the chromium(II) ions.
