In this work, a pincer‐type complex [Cp*Ir‐(SNPh)(SNHPh)(C 2 B 10 H 9 )] ( 2 ) was synthesized and its reactivity studied in detail. Interestingly, molecular hydrogen can induce the transformation between the metalloradical [Cp*Ir‐(SNPh) 2 (C 2 B 10 H 9 )] ( 5 . ) and 2 . A mixed‐valence complex, [(Cp*Ir) 2 ‐(SNPh) 2 (C 2 B 10 H 8 )] ( 7 .+ ), was also synthesized by one‐electron oxidation. Studies show that 7 .+ is fully delocalized, possessing a four‐centered‐one‐electron (S‐Ir‐Ir‐S) bonding interaction. DFT calculations were also in good agreement with the experimental results.
