Studies on the assembly of atomically precise metal nanoclusters (NCs) are of great significance in the nanomaterial field, which has attracted increasing interest in the last few decades. Herein, we report the cocrystallization of two negatively charged atom-precise silver nanoclusters, the octahedral [Ag(MNT)(TPP)] () and the truncated-tetrahedral [Ag(MNT)(TPP)] () in a 1:2 ratio (MNT = dimercaptomaleonitrile, TPP = triphenylphosphine). As far as we know, a cocrystal containing two negatively charged NCs has seldom been reported. Single-crystal structure determinations reveal that the component and NCs both adopt core-shell structures. In addition, the component NCs were separately obtained by adjusting the synthetic conditions. This work enriches the structural diversity of silver NCs and extends the family of cluster-based cocrystals.
对原子精确的金属纳米团簇（NCs）组装的研究在纳米材料领域具有重要意义，在过去几十年中引起了越来越多的关注。在此，我们报道了两种带负电荷的原子精确银纳米团簇，八面体[Ag(MNT)(TPP)]（）和截顶四面体[Ag(MNT)(TPP)]（）以1:2的比例共结晶（MNT = 二巯基马来腈，TPP = 三苯基膦）。据我们所知，很少有关于包含两个带负电荷的NCs的共晶体的报道。单晶结构测定表明，组分和NCs均采用核壳结构。此外，通过调整合成条件分别获得了组分NCs。这项工作丰富了银NCs的结构多样性，并扩展了基于团簇的共晶体家族。
