Coordination sphere vibrations in copper(II), nickel(II) and cobalt(II) complexes with 4-imidazoleacetic acid; metal isotope, deuteration, and density functional study

摘要

Low-frequency vibrational spectra of Cu(II), Ni(II) and Co(II) complexes with 4-imidazoleacetic acid (HIA) are discussed. Metal isotope and deuteration effects were measured and used to assign the metal-ligand vibrations. These effects were included in density functional calculations carried out for the [Cu(IA)(2)] complex. (C) 2003 Elsevier B.V. All rights reserved.
