The reaction of the asymmetric 3-aminomethylpyridine (3-amp) ligand with silver(I) tetrafluoroborate (AgBF4) producesan array of structural motifs that depend on the ratio of the reactants present and crystallization temperature. Witha 1:1 ratio of 3-amp to silver, either a folded macrocycle, 1a, or a linear coordination polymer, 1, is formed,depending upon whether the crystals are grown at -35 or 5 
C. A 3:2 ratio forms two-dimensional sheets of 2regardless of temperature of crystallization. The 2:1 ratio of ligand to metal again sees a temperature dependencewith either a one-dimensional, 3a, or two-dimensional, 3, coordination polymer formed upon crystallization at lowand high temperatures, respectively. Addition of 2,2'-bipyridine to any of the previous reaction mixtures stops theformation of their respective structures, instead constructing the discrete Ag-Ag-linked 4.
