The synthesis of a new family of coordination polymers [AgL 2X]n (1a, X = CF3SO3; 1b, X = BF4; 1c, X = NO3; 1d, X = PF6) using 5-methoxy-1,3-bis(pyridin-3-ylethynyl)benzene (L2) as the self-assembling ligand is described. All compounds have been fully characterized by spectroscopic techniques and elemental analysis. In particular the X-ray molecular structures of 1a and 1b are reported and confirm the formation of 1D silver(I) chains. Their arrangements are described as a function and the nature of the anion. The supramolecular product 1a exhibits argentophilic Ag···Ag interactions to afford infinite double chains. Additionally, I·1-AgI-π interactions lead to the formation of a network of stacked layers of double chains. In contrast, 1b lacks metal-counterion bonding and is constituted of infinite coordination polymers, which are held together by π-π interactions. The pivotal role of the counteranions on the overall packing arrangement of the polymers is presented and discussed.
