- W2022133505 abstract "The preparation and infrared spectroscopic studies of coordination compounds of salicylaldoxime, 2-hydroxy-acetophenone oxime, 2-hydroxy-benzophenone oxime and 2-hydroxy-4-methoxy-benzophenone oxime with copper(Ⅱ), nickel(Ⅱ), cobalt(Ⅱ) and iron(Ⅱ) have been described.The frequency of the C=N stretching vibration is usually higher in the complex than that in the ligand. The higher the frequency of the C=N vibration is, the larger the stability constant of the complex will be, but there is no quantitative relationship. In the case of complexes of salicylaldoxime with Cu, Ni, Co and Fe, v_(C=N) values are correlated linearly with the ionization potentials of the central metal ions.The frequency of the OH stretching vibration is closely related to the geometric configuration of the complex. Thus aromatic hydroxyoximes form coordination compound with Co(Ⅱ) and Fe(Ⅱ) with cis configuration possessing six membered stronger hydrogen bonding ring. This is indicated in the infrared spectra by the complete absence of the absorption band due to the OH stretching vibration, or by the appearance of an extremely broad and flat band of very low intensity. However, Cu(Ⅱ) or Ni(Ⅱ) complex possesses trans configuration with five membered hydrogen-bonding bridge showing characteristic OH absorption band in the infrared region. The v_(OH) of complex investigated is closely related to the polar nature of the substituents on the benzene ring.By examining the spectra of ~(63)Cu and ~(65)Cu complexes with 2-hydroxy-4(5)-substituted benzophenone oximes, the characteristic freuencies of M-O and M-N in the far infrared region were assigned for a series of aromatic hydroxyoxime-transition metal complexes." @default.
