The azanidodithiolate pincer ligand derived from bis(2-mercapto-p-tolyl)amine is capable of storing one proton and one electron when coordinated to a metal center. Coordination of the ligand to nickel and cobalt in the doubly deprotonated state affords complexes of the form [SN(H)S]ML (M = Ni, Co; L = phosphine) with a secondary amine donor that contains an acidic proton. Electrochemical and acid-base measurements have been used to determine N–H BDFEs while reactivity studies have been used to assess the ability of this hydrogen atom to participate in small-molecule activation reactions.
