Structural Study of Lanthanide Complexes Formed with o-Vanillin Salicyloylhydrazone and o-Vanillin Paraanisidine

Spectroscopy Letters, 1995
Abstract Ten lanthanide complexes (Ln=La, Ce, Pr, Nd, Sm, Gd, Eu and Dy) with the title ligands have been synthesised and characterised. The structure of these complexes are assigned on the basis of IR spectra, magnetic and thermal analysis data. The IR spectra indicate that o-vanillin paraanisidine (oVPA) is a bidentate ligand coordinating through ...
