Exploring the Assembly of Supramolecular Polyoxometalate Triangular Morphologies with Johnson Solid Cores: [(Mn-II(H2O)(3))(2)(K subset of{alpha-(GeW10Mn2O38)-O-II}(3))](19-)
A new polyoxometalate (POM) cluster compound is presented which incorporates a trimeric assembly of Keggin-type germanotungstate fragments trapping a Johnson-type solid {Mn-8} core. The mixed K-Li salt of the polyanion [(Mn-II(H2O)(3))(2) (K subset of{alpha-(GeW10Mn2O38)-O-II}(3))](19-) was characterized in the solid state and solution. The correlation of the assembly processes and the observed architecture of the "trinity" family of POMs is discussed.
