The effect of Fe(II) ions on the 1,10-phenanthroline and neocuproine intercalates of ?-zirconium phosphate

説明
1,10-Phenanthroline (phen), 2,9-dimethyl-1,10-phenanthroline (neocuproine), and 4,7-dimethyl-1,10-phenanthroline have been intercalated between layers of γ-zirconium phosphate (γ-ZrP). The observed interlayer distances are not a simple function of the size of guest molecules. Despite the fact that γ-ZrP takes up very few Fe2+ ions, the phen and neocuproine intercalates do take up some Fe2+ ions without further changes in the interlayer distances. The chemical environments around Fe2+ ions between layers of the intercalates were investigated by57Fe Mossbauer spectroscopy. A fairly large fraction of the Fe2+ ions was found to be in a high-spin state. The low-spin [Fe(phen)3]2+ ions are also ion exchanged on γ-ZrP, with the expansion of the interlayer up to 19.9 A.
