Inside Cover: Reactivities of Interstitial Hydrides in a Cu₁₁ Template: En Route to Bimetallic Clusters (Angew. Chem. Int. Ed. 2/2022)

Recent progress in dichalcophosphate coinage metal clusters and superatoms

“…9). 94 Interestingly, these reactions trigger the reactivity of the interstitial μ 4 -hydrides of the Cu 11 H 2 cluster, making them react like Lewis bases or reductants. To our knowledge, the interstitial hydrides behaving as Lewis bases have never been observed in heterometallic clusters.…”

Hydride‐containing 2‐Electron Pd/Cu Superatoms as Catalysts for Efficient Electrochemical Hydrogen Evolution

“…Herein first hydride-containing 2-electron palladium/ copper superatomic alloys co-protected by alkynyl and dithiophosphato ligands are prepared by the treatment of PdH 2 Cu 14 [17] with trifluoroacetic acid (TFA Lewis bases, reducing Pd II to Pd 0 and supplying the hydride ligand in PdHCu 11 . [22,23] Presumably, an aggregation occurs during the reaction, which leads to the addition of one alkynyl ligand in the yielded alloy cluster. Alternatively, PdHCu 11 can also be synthesized by the addition of two equiv.…”

Mechanistic insights into Ag+induced size-growth from [Au6(DPPP)4]2+to [Au7(DPPP)4]2+clusters

“…The stimuli response upon the exposure to extra metal ions represents an attractive characteristic of metal nanoclusters. [1][2][3][4][5][6][7][8] The structural response may be reflected in the complexation of the metal ion(s) with the surface ligands, [9][10][11] the doping/exchange/addition of the metal ion(s) into the metallic framework of the cluster, [12][13][14][15] the slightly changed structure with different charge state 16 or the re-arrangement of the entire cluster structure. [17][18][19][20] Meanwhile, enhanced physicochemical properties (such as thermostability) and novel applications [21][22][23] could be achieved due to the synergistic effect.…”
