摘要：

A spectroelectrochemical study of [Ru2X9]n-, X = Cl, Br; n = 1, 2, 3, 4 has been undertaken. Stable solutions of n = 4, 2, 1 can be formed by electrolysis at low temperatures. Analysis of the Vis-NIR spectra of the complexes indicate that the Ru(II)-R(III) dimers (n = 4) have delocalised mixed valence and that the Ru(III)-R(III) (n = 3) dimers have a strong Ru-Ru bond. The more oxidised materials do not form a Ru-Ru bond; the spectroscopic data indicates the Ru(III)-R(IV) dimers have localised valency.
