1D Chain-Like Architecture in Anderson Heteropolymolybdate {[Eu(H2O)6]2(TeMo6O24)}•6H2O: Synthesis and Characterization

A new Anderson-based heteropolymolybdate {[Eu(H2O)(6)](2)(TeMo6O24)}center dot 6H(2)O (1) has been hydrothermally synthesized and characterized by elemental analyses, IR, thermal stability analysis, XRD and single crystal X-ray diffraction. Compound 1 crystallizes in the triclinic system, space group P-1, a = 9.4023(6) , b = 10.2530(7) , c = 10.6525(10) , alpha = 101.583(7)A(0), beta A = 108.024(7)A(0), gamma A = 107.150(6)A(0), V = 883.60(12) (3), Z = 1, R-1 = 0.0338, wR(2) = 0.0849. Compound 1 exhibits 1D chain-like structure formed by the alternative connection between Anderson type polyoxoanions [TeMo6O24](6-) and Eu3+ along a-axis. Compound 1 displays good fluorescent emission of the Eu3+ ion at room temperature.
