In the title compound, [Cu(C6F5COO)2(C4H4N2)]n, (I), the asymmetric unit contains one CuIIcation, two anionic pentafluorobenzoate ligands and one pyrazine ligand. Each CuIIcentre is five-coordinated by three O atoms from three independent pentafluorobenzoate anions, as well as by two N atoms from two pyrazine ligands, giving rise to an approximately square-pyramidal coordination geometry. Adjacent CuIIcations are bridged by a pyrazine ligand and two pentafluorobenzoate anions to give a two-dimensional layer. The layers are stacked to generate a three-dimensional supramolecular architectureviastrong intermolecular C—H...F—C interactions, as indicated by the F...H distance of 2.38 Å.
