Redetermination of the Structure of La₂Cu₂O₅ by Neutron Powder Diffraction

The structure of La₂Cu₂O₅ comprises CuO₅ square pyramids connected to each other in three dimensions by corner sharing and ten-coordinate La³⁺ ions occupying positions next to oxygen vacancies which form tunnels along the c axis.

CsAg_0.64Mn_1.18Te₂

CsAg_0.64Mn_1.18Te₂ exhibits the ThCr₂Si₂ structure type, comprising slabs of Ag- and Mn-centered edge-sharing tetrahedra separated by Cs⁺ cations.

A New Europium Borosilicate, Eu₃BSi₂O₁₀

The structure of Eu₃BSi₂O₁₀ is composed of layers of isolated BSi1O₆⁵⁻ and Si2O₄⁴⁻ anions which alternate along the c axis. The layers are linked through three crystallographically independent Eu³⁺ ions to form a three-dimensional network structure.

KGaAs₂O₇

KGaAs₂O₇ is isostructural with KAlAs₂O₇. The framework is composed of GaO₆ octahedra joined through As₂O₇ groups by corner sharing, forming intersecting tunnels where the K⁺ cations are located.

LaMo₈O₁₄

The structure of LaMo₈O₁₄ contains an equal mixture of cis-edge-sharing and trans bi-face-capped octahedral Mo₈ clusters arranged in layers. The O-atom framework derives from close packing with an ABAC⋯ layer sequence. The La³⁺ ions are surrounded by 12 O atoms forming a distorted cuboctahedron.

Strontium Tetragermanate, SrGe₄O₉

SrGe₄O₉ comprises two different types of sheet structure stacked alternately along the c axis. One type of sheet comprises GeO₆ octahedra and SrO₈ polyhedra while the other contains three-membered rings of GeO₄ tetrahedra.
