rare example of three-coordinate T-shaped geometry at these atoms. In the dimers 2 and 3, each metal center is coordinated to a terminal terphenyl ligand and two bridging NMe2 groups to give a distorted trigonal planar geometry. In contrast, the reaction of LiNMe2 with Ar#Co(μ-I)}2 in a 2:1 ratio did not yield an amido product; instead, the NMe2 ligand underwent hydrogen elimination. As a result, in
