Ca2CuTe4O10Cl2, a new synthetic tellurium(IV) oxochloride.
Single crystals of dicalcium copper tetratellurium decaoxide dichloride, Ca2CuTe4O10Cl2, were synthesized via a transport reaction in sealed evacuated quartz glass tubes. The building units of the structure are irregular CaO7 polyhedra, centrosymmetric CuO4Cl2 octahedra and two crystallographically distinct TeO4E distorted bipyramids (E being the 5s2 lone pair of TeIV). The TeO4E and CuO4Cl2 polyhedra together form planes that are connected by the Ca atoms. The CuO4Cl2 octahedra are isolated from each other by the other building units.
