Structural diversity in coordination polymers constructed from a naphthalene-spaced dipyridyl ligand and iron(II) thiocyanate

Employing N,N'-bis-(4-pyridinylmethylene)-1,5-naphthalenediamine (nbpy4) and iron(II) thiocyanate as building blocks, three coordination polymers, [Fe(NCS)2(nbpy4)(MeOH)2]n, 1, [Fe(NCS)2(nbpy4)2]n_2nCHCl3_nH2O"¢2nEtOH, 2, and [Fe(NCS)2(nbpy4)(bpy)]n_2.5nDCM_0.75nH2O, 3, have been prepared. The three metal-organic materials were prepared by varying the solvent systems used and the inclusion of a second pyridine containing ligand (4,4"²-bipyridine, bpy). Single crystal X-ray diffraction revealed 1 to be a one-dimensional structure with hydrogen bonding between adjacent chains and 2-3 to be two-dimension network solids with (4,4)-topologies.
