Summary: Monodentate N-heterocyclic pyridine-, pyridinium- and bis-pyridinium aldoximes react with the aquapentacyanoferrate(II) ion (AqP) by forming usually coloured oximatopentacyanoferrate(II) compounds of a 1:1 molar ratio where are the oximes linked to the iron through the nitrogen of the oxime group. Dealing with bidentate oximes, depending on the preparation procedure, mononuclear or binuclear complexes may form, where beside water one cyanide ion from the metal reagent is also substituted. To our present knowledge, oxo-oximes and ortho-substituted nitrosonaphtols examined through this project, react with the AqP ion by forming cyano-bridged binuclear tetracyanoferrate(II) complexes. Mercury(II) ions are found to catalyse these reactions.

Keywords: Cyanoferrates(II), oximes

Research goals: The low-spin complexes of iron are model substancies in the examinations of interactions between metal and ligands in biological systems (proteins, enzymes, porphyrines etc.) On the other side many oximes are effective antidotes against organophosphorus poisoning (insecticides, nerve gases) so are the investigations of their reactions interesting regarding their biological properties as well as respecting the possibility of their specific analytical application for the detection and determination of micro amounts of oximes. The aim of this investigation is the learning of the reactions of different oximes with the pentacyanide complexes of iron and the establishement of the way of their bonding in a complex compound.
