Redox Induced S-S Bond Cleavage Of 2,2 '-Dithiobisbenzothiazole - Leading To A [2ru-2s] Core Analogous To [2fe-2s] Cluster

Facile reduction of 2,2 '-dithiobisbenzothiazole by the mediation of metal-to-ligand charge transfer or by internal reducing equivalent is demonstrated. It leads to various binding modes of thiolates (kappa(1), kappa(2), mu) in a series of mononuclear and dinuclear ruthenium complexes. The dinuclear complex exhibited electron transfer processes similar to a [2Fe-2S] cluster.
