Triangular and Tetrahedral Array of Silver(I) Ions by a Novel Disk-Shaped Tridentate Ligand:  Dynamic Control of Coordination Equilibrium of the Silver(I) Complexes

A disk-shaped tridentate ligand 1 arranges silver(I) ions in a two-dimensional triangular and a three-dimensional tetrahedral fashion in the metal−ligand ratios, 3:2 and 1:1, respectively. The resulting sandwich-type (Ag₃1₂) and tetrahedral (Ag₄1₄) architectures are in a dynamic equilibrium in solution.
