Two compounds, {l_brace}[Sm(H{sub 2}O){sub 5}]{sub 2}(TeMo{sub 6}O{sub 24}){r_brace}.6H{sub 2}O (1) and {l_brace}[Eu(H{sub 2}O){sub 7}]{sub 2} (TeMo{sub 6}O{sub 24}){r_brace}.5H{sub 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 [TeMo{sub 6}O{sub 24}]{sup 6-} and rare-earth ions Ln{sup 3+}. Compound 2 displays a 1D chain structure built up of alternating Anderson-type polyoxoanions [TeMo{sub 6}O{sub 24}]{sup 6-} and rare-earth ions Eu{sup 3+} along the c-axis. Luminescence measurement of 2 exhibits typical red fluorescent emission of the Eu{sup 3+} ion at room temperature. Furthermore, the emission is intense enough to be observed macroscopically under UV irradiation (365 nm). - Graphical abstract: Two compounds based on Anderson-type polyoxoanion building blocks and rare-earth ions have been synthesized under hydrothermal conditions. Compound 1 exhibits a 2D layer architecture constructed from [TeMo{sub 6}O{sub 24}]{sup 6-} anions and rare-earth ions Ln{sup 3+}. Compound 2 displays a 1D chain structure and possesses the intense luminescence property.
