Cover Picture: Facially Dispersed Polyhydride Cu 9 and Cu 16 Clusters Comprising Apex‐Truncated Supertetrahedral and Square‐Face‐Capped Cuboctahedral Copper Frameworks (Angew. Chem. Int. Ed. 6/2020)

Catalytic hydrogenation of CO 2 to formate is promoted by copper hydride clusters. Cage‐type copper hydride clusters prepared by using a tetraphosphine ligand, dpmppm, can have apex‐truncated supertetrahedral {Cu 9 H 7 } 2+ and square‐face‐capped cuboctahedral {Cu 16 H 14 } 2+ frameworks, or an unsymmetrical {Cu 8 H 6 } 2+ structure. As reported by T. Tanase and co‐workers in their Communication on page 2262, the kinetically trapped {Cu 8 H 6 } 2+ species promotes catalytic hydrogenation of CO 2 to formate in the presence of strong base.
