Sažetak
A detailed structural characterization of the title biologically active ligands was made by NMR, vibrational and electronic spectroscopy as well as by X-ray diffraction. Their complexes with the aquapentacyanoferrate(II) ion were examined in solution, isolated as solids and characterized by elemental analysis, electronic, IR and NMR spectral data. They are found to be mononuclear substituted pentacyanoferrates(II) containing the aldoxime group coordinated to the iron through the nitrogen atom. The complexes were also precipitated in the form of the respective zinc salts whose analysis revealed a molar Fe/Zn ratio of 1 confirming the charge of the complex anions to be -2. In spite of the presence of two donor sites in 1-phenacylpyridinium-4-aldoxime chloride, only the aldoxime group is found to be reactive.
