| Abstract: | The colour reactions of three bis-pyridinium aldoximes with ammine- and nitrosyl-pentacyanoferrate(II) ions were studied. The optimum reaction conditions, the compositions and the stability constants of the produced complexes were determined. The compelxes were isolated and characterized by elemental analysis, visible, UV and IR spectral data. The examined compounds, although dioximes, are found to form 1 : 1 complexes. |
