Abstract
Herein, a sandwich-type tungstoantimonate [Na(H2O)2]3[C3H5N2]2[SbW9O33]2[FeII(C3H4N2)]3·4H2O (1) has been synthesized using iron powder as a starting material under conventional reaction conditions. The structure of 1 was determined by single-crystal X-ray diffraction and further characterized by IR spectrum, UV-vis spectra, and diffuse reflectance spectrum. The successful synthesis of compound 1 demonstrates an effective method for the synthesis of FeII-based polyoxometalates. The functional applications of compound 1 in both photocatalytic degradation of methyl orange and electrochemical sensing of dopamine were also demonstrated experimentally.
