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