Sažetak
A detailed structural characterization of the title ligands was made by vibrational spectroscopy as well as by X-ray diffraction in the case of 1- phenacylpyridinium-4-aldoxime chloride. Their complexes with the aquapentacyanoferrate(II) ion were examined in solution, isolated as solids and characterized by elemental analysis, UV-Vis and IR spectral data. They are found to be substituted pentacyanoferrates(II) of the 1:1 molar ratio where is the oxime group linked to the iron through the nitrogen atom. The complexes were prepared also in the form of the respective zinc salts whose composition was deduced by particle induced X-ray emission analysis (PIXE). A Zn/Fe proportion of 1:1 was found, 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 oxime group is found to coordinate to the iron center.
