This study presents a new approach for improving the stability of metal nanoclusters by complicating the surface environment, which successfully endows Ag-29 nanoclusters with high robustness. A unique packing mode in the supracrystal lattice has also been observed.
Silver nanoclusters have received unprecedented attention in cluster science owing to their promising functionalities and intriguing physical/chemical properties. However, essential instability significantly impedes their extensive applications. We herein propose a strategy termed surface environment complication to endow Ag-29 nanoclusters with high robustness. The Ag-29(S-Adm)(18)(PPh3)(4) nanocluster with monodentate PPh3 ligands was extremely unstable and uncrystallizable. By substituting PPh3 with bidentate PPh(2)py with dual coordination sites (i.e., P and N), the Ag-29 cluster framework was twisted because of the generation of N-Ag interactions, and three NO3 ligands were further anchored onto the nanocluster surface, yielding a new Ag-29(S-Adm)(15)(NO3)(3)(PPh(2)py)(4) nanocluster with high stability. The metal-control or ligand-control effects on stabilizing the Ag-29 nanocluster were further evaluated. Besides, Ag-29(S-Adm)(15)(NO3)(3)(PPh(2)py)(4) followed a unique packing mode in the supracrystal lattice with several intercluster channels, which has yet been observed in other M-29 cluster crystals. Overall, this work presents a new approach (i.e., surface environment complication) for tailoring the surface environment and improving the stability of metal nanoclusters.
