• From a predesigned grid, [CuII5CuI4L6]⋅(I)2⋅13 H2O (1), in which LH2 was a pyrazinyl‐triazolyl‐2,6‐substituted pyridine, we successfully synthesized an extended 3D complex, 1∞[{CuII5CuI8L6}{μ‐[CuI3(CN)6]}2⋅2 CH3‐ CN] (2), that displayed unprecedented coexistence of all the five known coordination geometries of copper. Grid 1 displayed monovalent central metal exchange (CME) of CuI for AgI for the first time, as well as the formation of tri‐iodide in the crystalline state. These systems were investigated for their magnetic properties. Remarkably, grid 1 showed much higher catalytic activity than the Ag‐exchanged product for synthesis of a substituted triazole, 1‐benzyl‐4‐phenyl‐1H‐1,2,3‐triazole. Fast off the grid: A predesigned grid, [CuII5CuI4L6]⋅(I)2⋅13 H2O (1), was extended into a 3D 1∞[{CuII5CuI8L6}{μ‐[CuI3(CN)6]}2⋅2 CH3CN] network that showed the unprecedented coexistence of all five coordination geometries of copper. Grid 1 also displayed monovalent central‐metal exchange of CuI for AgI for the first time, as well as tri‐iodide formation in the crystalline state (see figure).
