 Title    Planare C u 0 4-Polygone und eine einseitig offene Te4+0 3-Koordination in SrCuTe20 6 Planar C u 0 4 Polygons and a One-Sided Open Te4+0 3 Coordination in SrCuTe-,06 L  
 Abstract    The new compound SrCuTe20 6 has been prepared by quenching single crystals grown from a flux of SrC 03, T e02 and C uC 03 C u(0H)2. X-ray investigations show cubic symmetry, space group 0 7-P4| 32, lattice constant a = 12.473(1), Z = 12. The crystal structure is characterized by square planar C u 0 4 polygons and a one-sided open triangular oxygen coordination of Te4+, both incorporated in a Sr/O network. The one sided oxygen coordination of tellurium is completed by the lone pair of Te4+. Calculations of the Coulomb parts of lattice energy led to the position of the lone pair centre.
