The structure of lanthanide complexes with benzoic acid was investigated by IR and UV absorption spectra.To determine the effect of metal coordination on the aromatic system of benzoic acid, IR spectra of Ln(OBz)3 (Ln is a lanthanide except promethium; BzO is benzoic acid radical) were compared with ligand and sodium benzoate spectra.Also, changes in frequency and relative intensity of the ν(C-C)ar bands in the 1600-1400 cm-1 region, were analyzed in terms of the atomic number of lanthanides.It is shown that lanthanides disturb the aromatic system of the benzoate ligand less than sodium.This effect is discussed in terms of the bond formed.
