H-type Ce2[Si2O7] by Ralf Jules Christian Locke, Maria Weis, Thomas Schleid

“…The four crystallographically distinct CeIII cations form distorted square antiprisms, capped square antiprisms, and bicapped square antiprisms as coordination polyhedra consisting of oxygen atoms. Four crystallographically different silicon atoms recruit the centers of two different isolated [Si2O7]6– units.…”

The Short Series of the Oxygen-Poor Lanthanide Oxide Selenides M10OSe14 with M = La–Nd by Frank A. Weber, Christian M. Schurz, Susanne Frunder, Charlotte F. Kuhn, Thomas Schleid

“…All three crystallographically independent M3+ cations exhibit eight contacts to chalcogenide anions (O2– and/or Se2–) resulting in the formation of bicapped trigonal prismatic coordination polyhedra. The optical band gaps of the oxide selenides M10OSe14 amount to values between 1.89 and 2.04 eV indicating wide band-gap semiconductors.…”

Synthesis under high pressure: crystal structure and properties of cubic Dy36O11F50[AsO3]12 ∙ H2O by Felix Christian Goerigk, Ralf Jules Christian Locke, Thomas Schleid

“…Its crystal structure exhibits isolated ψ1-tetrahedral [AsO3]3– anions, but both the coordination numbers and the linking schemes of the Dy3+-centered polyhedra differ significantly from the mostly layered structures described so far in literature. …”

A Challenge toward Novel Quaternary Sulfides SrLnCuS₃ (Ln = La, Nd, Tm): Unraveling Synthetic Pathways, Structures and Properties by Anna V. Ruseikina, Maxim V. Grigoriev, Leonid A. Solovyov, Vladimir A. Chernyshev, Aleksandr S. Aleksandrovsky, Alexander S. Krylov, Svetlana N. Krylova, Nikolai P. Shestakov, Dmitriy A. Velikanov, Alexander A. Garmonov, Alexey V. Matigorov, Marcel A. Eberle, Thomas Schleid, Damir A. Safin

“…A 3D crystal structure of SrTmCuS₃ is constructed from the SrS₆ trigonal prisms, TmS₆ octahedra and CuS₄ tetrahedra. The latter two polyhedra are packed together into 2D layers, which are separated by 1D chains (SrS₆)_n and 1D free channels. …”

Synthesis, Crystal Structure and Properties of the New Laminar Quaternary Tellurides Sr<i>Ln</i>CuTe₃ (<i>Ln</i> = Sm, Gd–Tm and Lu) by Anna V. Ruseikina, Maxim V. Grigoriev, Maxim S. Molokeev, Alexander A. Garmonov, Andrey V. Elyshev, Ralf J. C. Locke, Thomas Schleid

“…The distortion of the polyhedra [CuTe₄]^7– was compared for the whole series Sr<i>Ln</i>CuTe₃ by means of τ₄-descriptor for the four coordinating Te^2– anions, which revealed a decrease in the degree of distortion with a decreasing radius at <i>Ln</i>³⁺. …”
