dc.description.abstractThe 6-oxonicotinate (6-Onic) salts of a one-dimensional cationic cobalt(II) or nickel(II) coordination polymers with 4,40 -bipyridine (4,40 -bpy), namely {[Co(4,40 -bpy)(H2O)4 ](6-Onic)2 ·2H2O}n (1) and {[Ni(4,40 -bpy)(H2O)4 ](6-Onic)2 ·2H2O}n (2), were prepared hydrothermally by reactions of cobalt(II) nitrate hexahydrate or nickel(II) nitrate hexahydrate, respectively, 6-hydroxynicotinic acid and 4,40 -bipyridine in a mixture of ethanol and water. In the hydrogen-bonded frameworks of 1 and 2, the one-dimensional polymeric chains of {[M(4,40 -bpy)(H2O)4 ] 2+}n (M = Co, Ni), the 6-oxonicotinate anions and the lattice water molecules were assembled via strong intermolecular O–H···O and N–H···O hydrogen bonds and π–π interactions, leading to the formation of the representative hydrogen-bond ring motifs: trimeric R 2 3 (10) motif, the centrosymmetric tetrameric R 2 4 (8) and R 2 4 (12) motifs and the pentameric R 4 5 (12) motif. The isostructural coordination polymers 1 and 2 exhibited a different electrochemical behavior, as observed by cyclic voltammetry, which can be attributed to the nature of the metal ions (cobalt(II) vs. nickel(II)).en_US
