A hexa­gonal 2a,c superstructure of Ba₇F₁₂Cl₂

A new superstructure of Ba₇F₁₂Cl₂ has been synthesized under hydro­thermal conditions.

Bis(ammonium) tris­(hexa­aqua­magnesium) tetra­kis(hydrogen phosphite)

The structure of (NH₄)₂[Mg(H₂O)₆]₃(HPO₃)₄ consists of a compact assembly of [Mg(H₂O)₆]²⁺, HPO₃²⁻ and NH₄⁺ ions held together by an intricate network of hydrogen bonds.

PbZn_1/3Nb_2/3O₃ at 4.2 and 295 K

The relaxor ferroelectric Pb(Zn_1/3Nb_2/3)O₃, known as PZN, was found to be rhombohedral in R3m at both 4.2 and 295 K from very high resolution neutron powder diffraction data. Atomic coordinates at both temperatures show strong electric polarization.

Dirubidium fluoro­trioxophosphate, Rb₂PO₃F, at 290 and 130 K, and dicaesium fluoro­trioxophosphate, Cs₂PO₃F, at 240 and 100 K

The title structures belong to the β-K₂SO₄ family. Cs₂PO₃F is twinned owing to the proximity of its lattice parameters to those of the orthohexa­gonal cell. Phase transitions were observed in slightly humid samples at 175 and 177 K for Rb₂PO₃F and Cs₂PO₃F, respectively, but were not observed in well dried samples.
