title: The synthesis and structure of [Zn(TEMPO)2]2 and [Zn(μ-H)(μ(2)-η(1):η(1)-TEMPO)]6.
abstract: The commercially available radical TEMPO (2,2,6,6-tetramethylpiperidin-1-yloxy) reacts with [ZnCp*2] (1) to yield the homoleptic compound [Zn(TEMPO)2]2 (2) through coupling of two Cp* radicals. Compound 1 reacts with H2 to afford the hydride complex [Zn(μ-H)(μ(2)-η(1)-η(1)-TEMPO)]6 (3) featuring a planar Zn6H6 ring in the solid state. Preliminary data suggest that the formation of 3 proceeds via a radical mechanism.
