The reaction of Ni3(dppm)33-l)2 with sodium trichlorostannate affords the first tin-capped nickel cluster Ni3(dppm)33-l)(μ3 -SnCl3) (1). A site of coordinative unsaturation at tin can be introduced by the reaction of 1 with Tl[PF6] yielding the stannylene-capped cluster [Ni3(dppm)33-l)(μ3 -SnCl2)]+ (2). Clusters 1 and 2 were characterized by 31P NMR, X-ray diffraction, and cyclic voltammetry (CV). Clusters 1 and 2 exhibit single electron redox chemistries, [Ni3-(dppm)33-l)(μ3 -SnCl3)]0/.-, [Ni3(dppm)33-l)(μ3 -SnCl2)]+/0, that together comprise a redox equilibrium. Thus, electrochemical reduction of 1 produces first the 49e- cluster radical anion [Ni3-(dppm)33-l)(μ3 -SnCl3)].- which then yields the reduced form of 2, [Ni3(dppm)33-l)(μ3 -SnCl2)], upon chloride dissociation.
