A new dimanganese Keggin-type polyoxotungstate K-6[Mn2SiW10O37(OH)(H2O)]center dot 11H(2)O (1) with 1D chains was obtained from a one-pot solution approach. The title compound was characterized with a wide range of analytical techniques including single crystal X-ray diffraction as well as various spectroscopic techniques, and its magnetic behavior was investigated. The novel dimanganese-substituted Keggin ion of (1) is constructed from a divacant {SiW10O37} subunit incorporating Mn-II and Mn-III ions. The emerging building blocks self-organize into new 1D chain-like POM architectures via Mn-O-W bridges that are rarely observed among this compound class. Water oxidation performance and long-term structural stability of (1) were investigated.
