摘要:
A novel vanadium tellurite V4Te4O18 was synthesized by the hydrothermal reaction Of V2O5, Na2TeO3, CuCl2.6H(2)O, and water. Its structure was determined by elemental analyses, XPS spectra, TG analysis, IR spectrum and the single-crystal X-ray diffraction. The title compound crystallized in monoclinic system, space group P2(1)/c, a = 7.2475(14) Angstrom b = 9.4901(19) Angstrom, c = 10.073(2) Angstrom7 beta = 94.45(3)degrees, V = 690.7(2) Angstrom, Z = 2, lambda(MoKalpha) = 0.71073 Angstrom, (R(F) = 0.0316 for 1580 reflections). Data were collected on a Rigaku R-AXIS RAPID IP diffractometer at 293 K in the range of 2.82 < theta < 27.47degrees. The title compound exhibits a novel three-dimensional (313) framework, formed by VO6 octahedra, VO5 square pyramids, TeO4 folded squares, and TeO5 square pyramids via the corner- and/or edge-sharing mode. The 3D framework consists of two different types of one-dimensional (I D) tunnels parallel to a-axes. (C) 2003 Elsevier Inc. All rights reserved.
