Bidentate bridging base polymer complexes of acetylacetonatoiron(II) [Fe(acac)2L]n, where L=pyrazine(pyz), 4,4′-bipyridine(bpy),trans-1,2-bis(4-pyridyl)ethylene(bpe), 1,2-bis(4-pyridyl)ethane(bpa) and 4,4′-trimethylene bipyridine(tmbpy), have been prepared, characterized and oxidized by iodine to give a range of iron(III) and iron(II) complexes [Fe(acac)2L · Ix]n] in which the FeIII/FeII ratios were established by Mössbauer spectroscopy. The electric conductivities of compressed pellets of the polysalts were obtained. The conductivities and Mössbauer parameters (I.S. and Q.S.) both change with respect to the kind of bidentate bridging bases.
The conjugation of bridged ligand markedly affects the conductivity of the complexes.
