Synthesis and characterization of lanthanum(III) and neodymium(III) complexes containing various Schiff bases

摘要

Some new complexes of lanthanum(III) and neodymium(III) with different Schiff bases (derived from salicylaldehyde with 2-methyl-1-aminobenzene and 2-aminopyridine have been synthesized and characterized by elemental (La/Nd, C, H, N and Cl) analysis, magnetic susceptibility measurements and spectral (UV-Visible, IR and FAB-MS) data. The Schiff bases, such as salicylidine-2-methyl-1-aminobenzene (smabH) and salicylidene-2-aminopyridine (sapH), bind in a bidentate fashion with the metals. A tentative structure for these complexes are proposed and suggested coordination number(s) six around neodymium(III) and eight around lanthanum(III) metal ions in the respective complexes of lanthanum(III) and neodymium(III) chloride.
