Incoming molecular hydrogen breaks the RuS bridges in the diruthenium complex [Ru(py bu S 4 )] 2 (py bu S 4 2− =2,6‐bis(2‐sulfanyl‐3,5‐di‐ tert‐ butylphenylthio)dimethylpyridine(2−)) shown, and the HH bond is cleaved to give H + and H − in the resulting thiol‐protonated hydride [Ru(H)(py bu S 4 ‐H)]. The proposed mechanism of the heterolytic cleavage of H 2 at the RuS centers is intriguing and possibly relevant to the activation of H 2 by hydrogenases.
