Na_1.50Mn_2.48Al_0.85(PO₄)₃, a new synthetic alluaudite-type compound

The title compound, an Na–Mn–Al-bearing phosphate, has been synthesized by the hydro­thermal technique. The crystal structure is similar to that of the natural mineral alluaudite.

Twinning and structure of Eu_0.6Sr_0.4MnO₃

Eu_0.6Sr_0.4MnO₃ crystallizes with an ortho­rhom­bic (Pbnm) perovskite-type structure and displays split positions of the Eu³⁺ and Sr²⁺ cations.

New triple molybdates Cs₃LiCo₂(MoO₄)₄ and Rb₃LiZn₂(MoO₄)₄, filled derivatives of the Cs₆Zn₅(MoO₄)₈ type

Tricesium lithium dicobalt tetra­kis­(tetra­oxo­molybdate), Cs₃LiCo₂(MoO₄)₄, and trirubidium lithium dizinc tetra­kis­(tetra­oxo­molybdate), Rb₃LiZn₂(MoO₄)₄, are isotypic with Cs₆Zn₅(MoO₄)₈ and contain frameworks of MoO₄ and (M_2/3Li_1/3)O₄ tetra­hedra (M = Co and Zn) with alkaline cations in cubocta­hedral cavities. The frameworks are close to that of 12CaO·7Al₂O₃ and the cations repeat the Y₃Au₃Sb₄ structure.

Iron(III) di­hydrogenphosphate(I)

The structure of Fe(H₂PO₂)₃ consists of [001] chains of octa­hedral Fe³⁺ cations ( symmetry) bridged by bidentate hypophosphite anions.

Lead zinc borate, PbZn₂(BO₃)₂

PbZn₂(BO₃)₂ crystallizes in the space group Pccn, with the Pb atom at a site with imposed twofold symmetry. The compound represents a new structure type in which ZnBO₃ layers are bridged by Pb²⁺ cations, giving rise to a three-dimensional framework.
