Potassium Bis(α-nonatungstoarsenato)di­aqua­tetracobaltate(II) 23-Hydrate, K₁₀[Co₄(H₂O)₂(AsW₉O₃₄)₂].23H₂O

The centrosymmetric [Co₄(H₂O)₂(AsW₉O₃₄)₂]^10- anion in this compound contains two [α-B-AsW₉O₃₄]⁹⁻ units bonded to a central set of four coplanar Co²⁺ ions, two of which also carry a water ligand. It is closely isostructural with the corresponding anions containing (Zn,As), (Co,P) and (Mn,P) [J. Chem. Soc. Dalton Trans. (1986), 2699-2705; Inorg. Chem. (1993), 32, 3378-3381].

A Cubic Hydrated Sodium Zinc Phosphate with a Tetrahedral-Triangular Framework Topology, Na₆Zn₃(PO₄)₄.3H₂O

The semi-condensed tetrahedral zinc phosphate framework in Na₆Zn₃(PO₄)₄.3H₂O has an unusual structural feature: the tetrahedral atoms form only eight-membered rings, in contrast to the typical six- or four-membered rings commonly found for aluminosilicates or aluminophosphates.

Cs₅Mo₂₁S₂₃

Cs₅Mo₂₁S₂₃ is isostructral with Cs₅Mo₂₁Se₂₃. The Mo–S framework comprises Mo₂₁S₂₃ cluster units sharing their six terminal S atoms. The Cs⁺ cations are located either between the Mo₂₁S₂₃ cluster units or in channels along the c axis.

Cadmium Thio­sulfate Dihydrate

The polymeric structure of CdS₂O₃.2H₂O consists of tightly woven two-dimensional networks interconnected by hydrogen bonds. The Cd²⁺ environment is octahedral and the thiosulfate ion binds to four different cationic sites, in simple as well as in bridging modes.

Structure d'un Diphosphate Synthétique de Cobalt: Co₂P₂O₇

This new polymorph of Co₂P₂O₇ contains CoO₆ octahedra and P₂O₇ groups with an O—P—O angle of 180°. The CoO₆ octahedra share edges to form six-membered rings, which are further interconnected to form two-dimensional zigzag sheets parallel to (001). The P₂O₇ groups link these sheets to form a three-dimensional network.

Sb₂MoO₆, a Re-examination

Sb₂MoO₆ has an Aurivillius-type layered structure. The Mo atoms are located in distorted O-atom polyhedra and the Sb atoms have 3+2 coordination.

Cs₃H(SeO₄)₂ at 300K by High-Resolution Neutron Powder Diffraction

The layered structure of Cs₃H(SeO₄)₂ is built from Cs atoms coordinated by O atoms belonging to SeO₄ tetrahedra. These tetrahedra are linked into isolated pairs by hydrogen bonds. The Cs atoms and SeO₄ tetrahedra form mixed layers alternating with layers containing only Cs atoms.

A New Hexagonal κ Phase of Al–Cr–Ni

This new hexagonal Al–Cr–Ni phase contains six columnar clusters in the unit cell, each of which is formed from two icosahedral clusters.

Ca₃Y₂(Si₃O₉)₂

Ca₃Y₂(Si₃O₉)₂ contains triangular Si₃O₉ silicate rings. Ca and Y atoms are situated between Si₃O₉ layers and are coordinated by six, seven or eight O atoms of the Si₃O₉ rings.

Zirconium–Nickel, Zr₇Ni₁₀: Space Group Revision for the Stoichiometric Phase

In contrast to previous reports, Zr₇Ni₁₀ crystallizes at the stoichiometric composition with a centrosymmetric structure in space group Cmca.
