Abstract
The title polymeric compound, [Cu2I2(C8H7N3)2]n [C8H7N3 = 3-(1H-imidazol-2-yl)pyridine (HIPy), where HIPy comes from the in situ decarboxylation of 2-(pyridin-3-yl)-1H-imidazole-4,5-dicarboxylic acid (H3PyIDC)], was obtained under solvothermal conditions. Each CuI cation is in a distorted tetrahedral coordination environment defined by two iodide anions and two nitrogen atoms from two individual HIPy ligands. Two CuI atoms are connected by two HIPy ligands to form a dimer and these dimers are further bridged through the iodide atoms, leading to a chain structure extending parallel to [100]. Moreover, intermolecular N—H⋯I hydrogen bonds and weak π–π stacking interactions [centroid⋯centroid distances of 3.809 (4) Å, an interplanar separation of 3.345 (3) Å and a ring slippage of 1.822 Å] between pyridyl rings link the chains into a two-dimensional supramolecular network in the ac plane.
