The article reviews the development and applications of supramolecular coordination chemistry, focusing on the self-assembly of finite two- and three-dimensional ensembles. It highlights the importance of coordination-driven self-assembly, which uses metal-ligand bonds to control the assembly process, leading to well-defined and complex architectures. The review covers various design principles, including directional bonding, symmetry interaction, paneling, weak link, and dimetallic building blocks, each with specific applications and advantages. The article also discusses the synthesis and functional properties of 2D ensembles, such as molecular rhomboids, triangles, and squares, emphasizing the role of metal centers and ligands in guiding the assembly process. Additionally, it explores the dynamic equilibria and reversible processes involved in the formation of these assemblies, providing insights into their potential applications in molecular recognition, catalysis, and guest encapsulation.The article reviews the development and applications of supramolecular coordination chemistry, focusing on the self-assembly of finite two- and three-dimensional ensembles.
