An α-Keggin polyoxometalate completely constructed from the late transition metal CoII as poly atom

Abstract

We report a catalytic eight-cobalt-capped α-Keggin polyoxoazocobaltite with a highly symmetric structure completely constructed from the late transition-metal Co^II as a poly atom, [Co₂₀(OH)₂₄(MMT)₁₂(SO₄)](NO₃)₂·6H₂O (1) (MMT: 2-mercapto-5-methyl-1,3,4-thiadiazole). To the best of our knowledge, this is the first homometallic Co^II magnetic cluster bearing Keggin structure. It can serve as a potential catalyst in the styrene polymerization.
