Cobalt(II) coordination polymers with the mixed ligands – halonicotinates and bispyridyl derivatives

Coordination polymers have attracted a lot of interest due to their various functional properties and many possible applications e. g. in catalysis, gas and energy storage, gas separation, magnetism, luminescence, molecular sensing, biomedical imaging. Their electrochemical sensing ability is influenced by the type of the employed metal ions and organic ligands. Cobalt(II) coordination polymers are promising candidates for electrochemical sensing of various analytes e.g. cations, anions, organic molecules because of their great electrochemical performance. We have prepared three similar cobalt(II) coordination polymers with the mixed ligands – halonicotinates (6-chloronicotinate (6-Clnic) or 6-bromonicotinate (6-Brnic)) and bispyridyl derivatives (1, 2-bis(4-pyridyl)ethane (1, 2-bpan) or 1, 2-bis(4-pyridyl)ethene (1, 2-bpen)), [Co(6- Brnic)2(1, 2-bpan)]n (1), [Co(6-Brnic)2(1, 2-bpen)]n (2) and [Co(6-Clnic)2(1, 2-bpen)]n·xH2O (3). These compounds were obtained by reactions of cobalt(II) nitrate hexahydrate, a respective halonicotinate and a respective bispyridyl derivative in DMF solutions. The cobalt(II) ion is octahedrally coordinated with two O, O’-bidentate bridging halonicotinates and with a single O, O’-bidentate chelate halonicotinate ligand in the equatorial plane, whilst two bridging bispyridyl derivative ligands are placed in the axial positions, resulting with the formation of an infinite double polymeric chain. The adjacent cobalt(II) ions are also bridged by two O, O’-bidentate halonicotinate ligands within the chain. There are solvent accessible voids in the crystal structure of 3, occupied by disordered lattice water molecules.
