A series of silver(I) complexes [Ag(L)(NO3)]4, (L = 2-amino-5-iodopyrimidine), 1, [Ag(L)(PF6)]∞, 2, and [Ag(L)(ClO4)]∞, 3, have been prepared by the reactions of AgX (X = NO3−, PF6− and ClO4−, respectively) with L. All the complexes have been structurally characterized by X-ray crystallography, confirming that complex 1 forms sixteen–membered metallocycles interlinked by I⋯I and Ag⋯O interactions to create a porous structure. Complexes 2 and 3 form helical chains, with different periods of 22.584 and 11.465 A, respectively. In addition to the Ag⋯O interaction and hydrogen bonds, the unique discrete Ag⋯I⋯I⋯Ag and linear ⋯(Ag⋯I⋯I⋯Ag)n⋯ interactions with short I⋯I and Ag⋯I contacts were found in complexes 2 and 3, respectively, to support their supramolecular structures.
