Coordination polymers of Fe(III) with ligands derived from dinaphthyl-, dinaphthylthio- and dinaphthyldithiophosphinic acids

Abstract

The synthesis and the study of some coordination polymers derived from the interaction of the acetylacetonate of Fe(III) with dinaphthylphosphinic acid, dinaphthylthiophosphinic acid and dinaphthyldithiophosphinic acid are presented. The methods applied for the study were chemical analysis, gel chromatography, Mössbauer and IR absorption spectroscopy, X-ray diffraction and thermogravimetric analysis from which the kinedic parameters of the thermal decomposition reactions were determined. The semiconductive properties of the synthesized compounds were also examined. Based on the obtained experimental data and on literature indications, the structural formulae of these compounds were assigned.
