Abstract A new compound based on capped polyoxometalates (POMs), [Ag(phen)<inf>2</inf>]<inf>2</inf>(Agphen)<inf>2</inf>SiW<inf>12</inf>O<inf>40</inf> (phen = 1,10-phenanthroline), has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction analysis, infrared spectrum, UV-vis electronic spectrum, elemental analyses, and powder X-ray diffraction pattern. The structural feature of compound 1 is that each [SiW<inf>12</inf>O<inf>40</inf>]<sup>4 -</sup> (SiW<inf>12</inf>) cluster capped by two (Agphen)<sup>+</sup> fragments. To the best of our knowledge, the compound 1 represents the first example of hybrid compound based on bi-silver-capped POMs to date. The photocatalytic properties of compound 1 were also investigated in detail and the results of photocatalytic experiment show that compound 1 can be used as a photocatalyst towards the decomposition of organic pollutant methylene blue (MB).
