A non-twinned polymorph of CaTe₂O₅ from a hydro­thermally grown crystal

The crystal structure of hydro­thermally grown CaTe₂O₅ is made up of undulating ²_∞[Te₂O₅]²⁻ layers propagating parallel to (100) with the Te^IV atoms in fourfold coordination. Adjacent layers are linked by distorted [CaO₇] polyhedra along [100].

Sr, Ba and Cd arsenates with the apatite-type structure

The title compounds belong to the apatite family. Suitable single crystals were prepared under hydro­thermal conditions. All three structures consist of isolated slightly distorted AsO₄ tetra­hedra which are bridged by Sr²⁺ in Sr₅(AsO₄)₃F, by Sr²⁺/Ba²⁺ in (Sr_1.66Ba_0.34)­(Ba_2.61Sr_0.39)­(AsO₄)₃Cl and by Cd²⁺ in Cd₅(AsO₄)₃Cl_0.58(OH)_0.42.
