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

M. Weil and B. Stöger

Synopsis: 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].

Formula: CaTe₂O₅

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

T. Đordevic, S. Sutovic, J. Stojanovic and Lj. Karanovic

Synopsis: 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.

Formula: Sr₅(AsO₄)₃F, (Sr_1.66Ba_0.34)(Ba_2.61Sr_0.39)(AsO₄)₃Cl and Cd₅(AsO₄)₃Cl_10.58(OH)_0.42
