Despite the remarkable progress made on intercluster conversion in atomically precise metal nanoclusters (MNCs) and their self‐organization to develop microscopic molecular architecture with well‐defined size and shape, achieving light‐induced reversible structural transformation and the development of micro‐ring self‐assembly in MNCs have, so far, remained elusive. The present investigation touches on these two long‐standing quests by showcasing a new route, light‐induced Particle‐Assisted Reversible Interconversion (PARI) for the reversible transformation from Face Centered Cubic (FCC) Ag14NCs to Ag7NCs. Our studies reveal that the lack of plasmonic silver nanoparticles (AgNPs) in the system results in the formation of Ag7NCs with centrosymmetric metallic kernels having hexagonal crystal packing. The molecular self‐organization of Ag7NCs through various non‐covalent interactions such as C‐H•••O, C‐H•••H‐C, and C‐H•••ᴨ leads to the formation of micro‐ring morphology, a unique molecular architecture in MNCs. The in‐situ generated AgNPs due to the acceleration of the reaction kinetics by Cu2+ ions facilitate the growth of Ag14NCs with FCC metallic kernel. These two structural units of AgNCs show light‐induced reversible structural transformation which is also associated with the reversible tuning of their spectroscopic and morphological signatures. This PARI‐guided interconversion strategy put forward a most appropriate example of a structure‐property relationship in MNCs.
