A series of novel
lanthanide-containing peroxo-isopolyoxomolybdates,
Na2(NH4)3[H3Ln6(H2O)26(MoO4){Mo7O22(O2)2}4]·nH2O [n = 24; Ln = CeIII (1), PrIII (2), SmIII (3), EuIII (4); n =
25; Ln = NdIII (5)] and Na4(NH4)3[H4La5(H2O)21(MoO4){Mo7O22(O2)2}4]·17H2O (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 [Ln4(H2O)16(MoO4){Mo7O22(O2)2}4]14– polyoxoanion. 1–5 can further generate two-dimensional structures through
LnIII cations, whereas 6 shows the one-dimensional
chain structure linked by LaIII cations. These compounds
represent the first examples of introducing peroxo groups into the
lanthanide-containing 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 SmIII and EuIII cations.
