Abstract

The combined use of bipy (4,4′-bipyridine) and dca (dicyanamide) has led to the preparation of two polymeric compounds of formulae [Fe(dca)2bipy(H2O)]·1/2H2O (1) and [Ni(dca)2bipy] (2). Both have been synthesised and characterised through IR and UV-Vis spectroscopies, thermal analysis, X-ray difracction and measurements of the molar magnetic susceptibility. Compound 1 is 1D and exhibits weak antiferromagnetic interactions. Compound 2 consists of two interpenetrated 3D networks giving rise to weak ferromagnetic interactions. The formation of both types of structure can be related to the different Pearson acidities of FeII and NiII ions.
