Synthesis and properties of biologically active o-, m- and p-isomers of N-substituted mono- and bis(pyridinium aldoximes) and their cyano complexes of iron(II)

The relationship between structural and chemical properties of synthesized o-, m- and p-isomers of monoaldoxime derivatives of the pyridinium cation and their bis(pyridinium aldoxime) analogues has been established by means of spectroscopic techniques and X-ray diffraction. Ionization ability in the order o- > p- > m-isomer, determined in aqueous media, was found to be in good agreement with their…
