The synthesis and structure of [Zn(TEMPO) sub(2)] sub(2) and [Zn( mu -H)( mu super(2)- eta super(1): eta super(1)-TEMPO)] sub(6)

The commercially available radical TEMPO (2,2,6,6-tetramethylpiperidin-1-yloxy) reacts with [ZnCp* sub(2)] (1) to yield the homoleptic compound [Zn(TEMPO) sub(2)] sub(2) (2) through coupling of two Cp* radicals. Compound 1 reacts with H sub(2) to afford the hydride complex [Zn( mu -H)( mu super(2)-...

Summary:The commercially available radical TEMPO (2,2,6,6-tetramethylpiperidin-1-yloxy) reacts with [ZnCp* sub(2)] (1) to yield the homoleptic compound [Zn(TEMPO) sub(2)] sub(2) (2) through coupling of two Cp* radicals. Compound 1 reacts with H sub(2) to afford the hydride complex [Zn( mu -H)( mu super(2)- eta super(1)- eta super(1)-TEMPO)] sub(6) (3) featuring a planar Zn sub(6)H sub(6) ring in the solid state. Preliminary data suggest that the formation of 3 proceeds viaa radical mechanism.
