Fedin «Coordination-Induced Condensation of [Ta6O19]8−: Synthesis and Structure of [{(C6H6)Ru}2Ta6O19]4– and [{(C6H6)RuTa6O18}2(μ-O)]10−» Inorg. Chem., 2014, 53 (24), pp 12791–12798 DOI: 10.1021/ic501622t

Reaction of [(C6H6)RuCl2]2 and Na8[Ta6O19] gives two new hybrid organometallic POM complexes, Na10[{(C6H6)RuTa6O18}2(μ-O)]∙39.4H2O and Na4(trans-[{(C6H6)Ru}2Ta6O19]∙20H2O. 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. 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
