La (III) and Ce (III) Complexes of Some Tri‐and Tetradentate N‐Naphthylideneamino Acids
The metal complexes of lanthanum(III) and cerium(III) with Schiff bases derived from the condensation of 2‐hydroxy‐1‐naphthaldehyde with _α_‐amino acids, viz. glycine, alanine, phenylalanine, valine, leucine and L‐glutamine, have been prepared and studied. The structures of these complexes are assigned on the basis of elemental analyses, molar conductance, IR and 1H NMR spectra and thermal analyses data. The results suggest that ... إقراء المزيد
