K-site splitting in KTiOPO₄ at room temperature

High-resolution synchrotron data have been used to determine the splitting of K sites in the Pna2₁ structure of KTiOPO₄ (KTP) at room temperature.

Ag₂Hg₂(TeO₄)₃

The crystal structure of Ag₂Hg₂(TeO₄)₃ is made up of _∞¹[(TeO_2/1O_4/2)({TeO_2/1O_2/2}₂O_4/2)] chains with Te^VI in octa­hedral coordination. The chains are linked by distorted AgO₆ and HgO₆ polyhedra into a three-dimensional network.

Ca₂CuTe₄O₁₀Cl₂, a new synthetic tellurium(IV) oxochloride

A new three-dimensional bimetallic tellurium halogenide, Ca₂CuTe₄O₁₀Cl₂, was synthesized by a transport reaction starting with CaO, CuO, CuCl₂ and TeO₂, and was characterized by single-crystal X-ray diffraction. The three-dimensional framework is built from anionic {[CuTe₄O₁₀Cl₂]₄}ⁿ⁻ layers parallel to (00) and connected via Ca—O bonds. The anionic layers are formed by two types of polyhedra, namely centrosymmetric CuO₄Cl₂ octa­hedra and TeO₄E distorted bipyramids (E being the 5s² lone pair of Te^IV).
