N2 - Reaction of a (benzene)Ru2+ complex, [Ru(C6H6)Cl2]2, with a di-lacunary γ-Keggin-type silicodecatungstate, K8[γ-SiW10O36], at a (C6H6)Ru2+/[γ-SiW10O36]8– ratio of 1 produces [γ-SiW10O36Ru(C6H6)]6–. The cesium salt was characterized using experimental and theoretical methods; one (C6H6)Ru2+ moiety is attached through three bridging oxygen atoms of the non-lacunary site, and the anion is stable in aqueous solution. 1H NMR spectroscopy and high-resolution electrospray ionization mass spectrometry measurements of the reaction mixture with different (C6H6)Ru2+/[γ-SiW10O36]8– ratios indicate that the (C6H6)Ru2+ complex first reacts with the three bridging oxygen atoms to form [γ-SiW10O36Ru(C6H6)]6–, and then react on the terminal oxygen atoms of the lacunary site to form a [γ-SiW10O36Ru(C6H6)]6– complex, which was reported by the Kortz and Nadjo group.
