Abstract
Five cobalt(II) complexes with 4,4′-bipyridine-N,N′-dioxide have been prepared and characterised. Their topology and dimensionality depend on the counteranion used: for Br− and Cl− the structures are layered inorganic/organic salts; I− forms a 3D supramolecular network while both NO3 − and SO4 2− induce the formation of interdigitated layer structures (with different coordination spheres) with a hydrophilic region between the Co(II) ions. The nitrate structure undergoes a reversible order–disorder phase transition at ca. 162 K. In all five complexes, ππ interactions are present between the bpdo molecules, possibly providing a directing force for the formation of these structures.Keywords
