摘要：

Single crystals of Sr3Te4O11 were grown from SrTeO3-TeO2 melts. Sr3Te4O11 crystallizes in the triclinic system, space group P1 (No. 1). The lattice parameters are a = 7.531(1), b = 9.240(1), c = 9.546(2) Angstrom, alpha = 98.07(1)degrees, beta = 109.55(1)degrees, gamma = 102.19(1)degrees, Z = 2. The Sr3Te4O11 crystal structure has been solved by X-ray single-crystal techniques up to a final R-value 0.0455 and wR(2)-value 0.1245 (SHELXL-93 software package) using 2490 observed reflections. Sr3Te4O11 forms a three-dimensional lattice consisting of trigonal TeO3 pyramids, trigonal TeO4 bipyramids, and irregular polyhedra (with 7, 8, or 9 apices) of Sr. (C) 1999 Elsevier Science Ltd.
