A series of novel lanthanide-containing peroxoisopolyoxomolybdates, Na-2(NH4)(3)[H(3)Ln(6)(H2O)(26)(MoO4)center dot{Mo(7)O(4)22(O-2)(2)}(4)]center dot nH(2)O [n = 24; Ln = Ce-III (1)p Pr-III (2), Sm-III (3), Eu-III (4); n = 25; Ln = Nd-III (5)] and Na-4(NH4)3 [H4La5 (H2O)(21)(MoO4){Mo7O22 (O-2)(2)}(4)]center dot 17H(2)O (6) have successfully been synthesized by the conventional method and further characterized by elemental analyses, X-ray photoelectron spectroscopy, X-ray powder diffraction, IR and UV spectra, thermogravimetric analyses, and single-crystal X-ray diffraction. All of the six compounds are composed of the [Ln(4)(H2O)(16)(MoO4){Mo7O22(O-2)(2)}(4)](14-) polyoxoanion. 1-5 can further generate two-dimensional structures through Ln(III) cations, whereas 6 shows the one-dimensional chain structure linked by La-III isopolyoxomolybdates. 1 is selected as an example to investigate the electrochemical behavior of these compounds. In addition, the fluorescence analyses of 3 and 4 have been studied. The spectra exhibit obvious fluorescence signals of Sm-III and Eu-III cations.
