Reaction of [(C6H6)RuCl2]2 and Na8[Ta6O19] gives two new hybrid organometallic POM complexes, Na10[{(C6H6)RuTa6O18}2(μ-O)]·39.4H2O (Na10-1) and Na4(trans-[{(C6H6)Ru}2Ta6O19]·20H2O (Na4-2). In both cases the half-sandwich fragments {(C6H6)Ru}2+ are coordinated as additional vertices to the {Ta3(μ2-O)3} triangles of the hexatantalate. According to NMR and ESI-MS data, the dimeric complex [{(C6H6)RuTa6O18}2(μ-O)]10- dissociates in water with the formation of monomeric [(C6H6)RuTa6O19]6– species (1a). X-ray structural characterization and aqueous speciation of the complexes by 13C, 1H, and DOSY NMR; ESI-MS; and capillary electrophoresis (CE) have been carried out.
