The commercially available radical TEMPO (2,2,6,6-tetramethylpiperidin-1-yloxy) reacts with [ZnCp2] (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.
市售的自由基TEMPO（2,2,6,6-四甲基哌啶-1-氧基）与[ZnCp2]（1）反应，通过两个Cp自由基的偶联生成同配化合物[Zn(TEMPO)2]2（2）。化合物1与H2反应得到氢化物配合物[Zn(μ-H)(μ(2)-η(1)-η(1)-TEMPO)]6（3），其在固态中具有平面Zn6H6环。初步数据表明，3的形成是通过自由基机理进行的。
