Hybrid polyoxometalate clusters with appended aromatic platforms

The assembly of polyoxometalate architectures based on Mn-Anderson clusters capped with different aromatic platforms via the 'Tris' linker (Tris tris(hydroxymethyl) aminomethane), allows the formation and isolation of four new hybrid polyoxometalate clusters of 2-5 with the general composition of [n-N(C4H9)(4)](3)[MnMo6O18{(OCH2)(3)CN = CH-R}(2)]center dot solv., (R = (C6H5) 2, -(C6H5O) 3, -(C11H8N) 4 and -(C13H9) 5; solv. MeOH or H2O). These compounds were obtained simply by the reaction of compound 1, ([n-N(C4H9)(4)](3)[MnMo6O18{(OCH2)(3)CNH2}(2)]), with the corresponding aldehyde and the aromatic platforms were chosen to explore the design principles for covalently constructed POM aromatic-organic-inorganic hybrids.
