Low-Temperature Form of LiGaSi₂O₆

The structure of the low-temperature form of LiGaSi₂O₆ has been determined from diffractometer data obtained at 273K. The structure is similar to that of pigeonite.

TaOI₂: Eine zentrosymmetrische Variante der NbOI₂-Struktur

TaOI₂ contains sheets of distorted TaO₂I₄ octahedra which share trans I–I edges and trans O corners. . The Ta atoms are displaced from the centres of the octahedra forming Ta⋯Ta pairs.

BaNaBO₃

The simple orthoborate BaNaBO₃ contains BaO₉ polyhedra and chains of face-sharing Na-centered octahedra which are bridged by BO₃ groups.

Samarium Tantalum Oxysulfide, Sm₂Ta₃S₂O₈

Sm₂Ta₃S₂O₈ is isostructural with La₂Ta₃S₂O₈. The structure comprises alternate layers of Sm tricapped trigonal prisms and Ta octahedra.

Redétermination de la Structure du Sulfure de Cadmium et de Germanium, Cd₄GeS₆

The structure of Cd₄GeS₆ comprises GeS₄ and CdS₄ tetrahedra. Each vertex of a GeS₄ tetrahedron is shared with two CdS₄ tetrahedra.

Ba[H₃IO₆]

Barium orthoperiodate adopts a structure which consists of Ba²⁺ and (H₃IO₆)²⁻ ions. The H atom is positionally disordered and the IO₆ octahedra are linked by O-H⋯O hydrogen bonds to form a three-dimensional network.

KYP₄O₁₂

KYP₄O₁₂ is isostructural with RbNdP₄O₁₂. The structure contains centrosymmetric P₄O₁₂ rings and YO₈ polyhedra.

Caesium–Lithium Phyllosilicate, Cs_1.33Li_0.67Si₂O₅

Cs_1.33Li_0.67Si₂O₅ exhibits a novel sheet topology with four-eight-twelve-membered rings. The sheets are interconnected by Li atoms, threefold coordinated by non-bridging O atoms, forming tunnels in which the Cs atoms are located.

Czochralski-Grown SrLaGaO₄

Lanthanum strontium tetraoxogallate adopts a K₂NiF₄-type structure. Sr^II and La^III are distributed statistically on one site and Ga^III has a stretched octahedral coordination geometry.
