Abstract
Two 2D-polymers of Cu(I), [Cu2(μ-tp)(CH3CN)(μ-I)(μ3-I)]n (1) and [Cu2(μ-tp)(μ3-I)2]n (2), both obtained from the reaction between copper iodide and 1,2,4-triazolo[1,5-a]pyrimidine (tp) in the presence of KI are described. While in compound 1, tp acts as bridging ligand via N1 and N3 between chair-like [Cu4I4] units, in compound 2, tp moieties are placed at both sides of a [CunIn] kinked layer, displaying also a bridging mode but, in this case, through its atoms N3 and N4. These structural differences between both compounds seem to be due to the solvent of crystallization, being acetonitrile for 1 and water for 2. These polymers are the first examples of Cu(I) compounds based on the nucleobase-analog ligand tp.
