Article Abstract
The assembly of heterometallic cluster substituted polyoxometalates (POMs) remains a great challenge for inorganic synthetic chemistry up to now. Herein, a series of 5p-4f heterometallic cluster substituted POMs were successfully isolated by a facile one-step hydrothermal reaction method, namely H(Hen)[SbSbLnO(HO)][(SbWO)(PWO)]·28HO(, Ln = Ce, Sm, Eu, Gd, Tb, Dy) (en = ethylenediamine). Interestingly, by replacing en with imidazole, another series of 5p-4f heterometallic cluster substituted POMs H(HIm)KNa(HO)[SbSbLnO(HO)][(SbWO)(PWO)]·26HO (, Ln = Sm, Eu, Gd, Tb, Dy, Im = imidazole) were obtained. Structural analyses indicate that both and are made up of an unprecedented 5p-4f heterometallic {SbLnO(HO)} cluster stabilized simultaneously by mixed trilacunary heteropolyanions including {A-α-PWO} and {B-α-SbWO}. Impedance measurements indicate that both compounds exhibit different proton conduction properties, and the conductivity of can reach up to 1.64 × 10 S cm at 85 °C under 98% relative humidity. Moreover, the fluorescence emission behaviors of both compounds have been studied.
