摘要：

Two compounds, {[Sm(H2O)(5)](2)(TeMo6O24))center dot 6H(2)O (1) and ([Eu(H2O)(7)](2) (TeMo6O24)}center dot 5H(2)O (2) have been synthesized by hydrothermal reactions and characterized by elemental analyses, IR spectra, thermal stability analyses, X-ray powder diffraction, and single-crystal X-ray diffraction. Compound 1 represents the first example of a 2D layer architecture constructed from Anderson-type polyoxoanions [TeMo6O24](6-) and rare-earth ions Ln(3+). Compound 2 displays a 1D chain structure built up of alternating Anderson-type polyoxoanions [TeMo6O24](6-) and rare-earth ions Eu3+ along the c-axis. Luminescence measurement of 2 exhibits typical red fluorescent emission of the Eu3+ ion at room temperature. Furthermore, the emission is intense enough to be observed macroscopically under UV irradiation (365 nm). (C) 2008 Published by Elsevier Inc.
