Front Cover: Dynamic Copper(I) and Silver(I) Complexes of Tri‐ tert ‐butyl‐cyclotriphosphane

From alchemical glow to digital insight : the evolution of phosphorus chemistry. Cyclotriphosphane ligands, stabilized by bulky tert ‐butyl groups, echo the symbol of elemental phosphorus. Modern tools like XRD, NMR and DFT now illuminate molecular structures and their unique binding modes—yet the spark of discovery remains timeless.
