Copper hydride cluster Cu 8 (μ‐H) 6 (μ‐dppm) 5 ](PF 6 ) 2 (dppm=bis(diphenylphosphino)methane) was prepared and characterized, and exhibited fluxional behaviors in solution where the hydrides and the phosphines are scrambling around the trans ‐bicapped octahedral Cu 8 framework. The Cu 8 H 6 complex readily reacted with CO 2 (1 atm, RT) to afford a trinuclear complex, [Cu 3 (μ‐H)(μ‐O 2 CH)(μ‐dppm) 3 ]PF 6 . Both complexes also promoted catalytic hydrosilylation of CO 2 under mild conditions, which is very unusual for Cu‐H clusters. More information can be found in the Communication by T. Tanase et al. on page 9457.
