Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>From a predesigned grid, [Cu^II₅Cu^I₄L₆]<bold>⋅</bold>(I)₂<bold>⋅</bold>13 H₂O (<bold>1</bold>), in which LH₂ was a pyrazinyl‐triazolyl‐2, 6‐substituted pyridine, we successfully synthesized an extended 3D complex, ¹_∞[{Cu^II₅Cu^I₈L₆}{μ‐[Cu^I₃(CN)₆]}₂<bold>⋅</bold>2 CH₃‐ CN] (<bold>2</bold>), that displayed unprecedented coexistence of all the five known coordination geometries of copper. Grid <bold>1</bold> 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 <bold>1</bold> showed much higher catalytic activity than the Ag‐exchanged product for synthesis of a substituted triazole, 1‐benzyl‐4‐phenyl‐1<italic>H</italic>‐1, 2, 3‐triazole.</p> </abstract>
