Abstract

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′-bipyridine, bpy). Single crystal X-ray diffraction revealed 1 to be a one-dimensional structure with hydrogen bonding between adjacent chains and 23 to be two-dimension network solids with (4,4)-topologies.

This work is dedicated to Professor Len Lindoy on the occasion of his 75th birthday.
