title: Post-synthetic monovalent central-metal exchange, specific I2 sensing, and polymerization of a catalytic [3×3] grid of [Cu(II)5Cu(I)4L6]⋅(I)2⋅13 H2O.
abstract: From a predesigned grid, [Cu(II)5Cu(I)4L6]⋅(I)2⋅13 H2O (1), in which LH2 was a pyrazinyl-triazolyl-2,6-substituted pyridine, we successfully synthesized an extended 3D complex, (1)∞[{Cu(II)5Cu(I)8L6}{μ-[Cu(I)3(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 Cu(I) for Ag(I) 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.
