Abstract

Abstract: Cocrystallization is a phenomenon involving the assembly of two or more different chemical entities in a lattice, occurring typically through supramolecular interactions. In this concept, recent advancements in the cocrystallization of atomically precise noble metal clusters and their potential future directions are presented. Different strategies to create coassemblies of thiolate‐protected noble metal nanoclusters are presented first. An approach is the simultaneous synthesis, and cocrystallization of two clusters having similar structures. A unique pair of clusters found recently, namely Ag40 and Ag46 with same core but different shell are taken to illustrate this. In another category, the case of the same core is presented, namely Ag116 with different shells, as in a mixture of Ag210 and Ag211 . Next, an intercluster reaction is presented to create cocrystals through selective crystallization of the reaction products. The coexistence of competing effects, magic sizes, and magic electron shells in a coassembly of alloy nanoclusters is discussed next. Finally, an assembly strategy for nanoclusters using electrostatic interactions is described. This concept is concluded with a future perspective on the emerging possibilities of such solids. Advancements in this field will certainly help the development of novel materials with exciting properties. Abstract : Cocrystallization encompasses the study of multicomponent crystalline solids as well as their design principles. This Concept presents recent advancements in the cocrystallization of atomically precise noble metal cluster systems. The concept of cocrystallization of structurally similar atomically precise nanoclusters, leading to new solids by different approaches is demonstrated.
