Ag₂Hg₂(TeO₄)₃

M. Weil

Synopsis: 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

R. Takagi and M. Johnsson

Synopsis: 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 (0 $\overline{1}$ 0) 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).

Formula: Ca₂CuTe₄O₁₀Cl₂
