Hexa­aqua­dodeca-μ-bromo-octahedro-hexatantalum bromide chloride octahydrate

A new compound with the [Ta₆Br₁₂(H₂O)₆]²⁺ cluster cation is isoconfigurational with the double salts [Ta₆Br₁₂(H₂O)₆]X₂·trans-[Ta₆Br₁₂(OH)₄(H₂O)₂]·18H₂O (X = Cl, Br).

Dilithium barium diphosphate

The crystal structure of Li₂BaP₂O₇ has been refined in monoclinic space group C2/c. Tunnels parallel to the (010) plane house Li atoms. A previous report of the structure in orthorhombic space group Cmcm included no R factor or positional parameters.

NaMn₆(P₂O₇)₂(P₃O₁₀) and KCd₆(P₂O₇)₂(P₃O₁₀)

The two title compounds crystallize with a layer structure housing tunnels which contain the alkali metal atoms.

KZn(HP₂O₇)·2H₂O and KMn(HP₂O₇)·2H₂O: acid pyrophosphate metallates(II) with layer structures

The crystal structures of the title compounds consist of acidic pyrophosphate–metallate(II) layers joined by K⁺ ions and hydrogen-bridging bonds. The Zn²⁺/Mn²⁺ ions are octahedrally surrounded by four pyrophosphate O atoms and by two water mol­ecules. The (HP₂O₇)³⁻ anions exhibit eclipsed conformations.

Synthetic hydro­cerussite, 2PbCO₃·Pb(OH)₂, by X-ray powder diffraction

The atomic arrangement of hydro­cerussite is closely related to the structures of other lead hydro­xide carbonates. It can be viewed as a sequence of two types of layers stacked along [001].

K₂SrNb₆Cl₁₈, dipotassium strontium hexaniobium octadecachloride

The structure of the title compound is based on [Nb₆Clⁱ₁₂Cl^a₆]⁴⁻ cluster anions (i and a denote `inner' and `outer' ligands, respectively), linked together by K⁺ and Sr²⁺ cations
