Abstract
An excellent fit to a symmetric adamantanoid ''Ru4O64+'' core arrangem ent 1 (Ru-O mu, 1.83 Angstrom; Ru-OH2, 2.16 Angstrom; and Ru-Ru, 3.4 A ngstrom) has been obtained from a ruthenium K edge EXAFS study on the tetrameric aqua ruthenium(IV) cation in both aqueous 2 M perchloric an d nitric acid solution. Mononuclear ''ruthenyl'' and tetranuclear hydr oxo-bridged formulations such as Ru-4(OH)(12)(4+)(aq) can now be unequ ivocally ruled out as relevant to the core structure. [GRAPHICS] PHICS ]
