Compound 1 was characterized by elemental analysis, infrared spectra, thermogravimetric analysis, and single-crystal X-ray diffraction. Structural analysis reveals that AsO2(OH)2− asymmetrically decorated the POM framework, constituting the first inorganic anion asymmetrically decorating a POM. AC measurements of the frequency-dependent χ′′ below 5 K indicated a slow magnetization relaxation in 1, resembling typical single-molecule-magnet behavior. Photocatalytic experiments indicated that introduction of AsO2(OH)2− may offer new active sites and enhanced the overall photocatalytic activity compared with the C-type precursor. ER -
