Synthesis and Characterization of Lanthanide(III) Ion Complexes with 2-Methoxy-4-amino-5-chloro-N-[2-(diethylamino)ethyl]benzamide

Abstract

Complexes of 2-methoxy-4-amino-5-chloro-N-[2-(diethylamino)
ethyl] benzamide with lanthanide(III) ions of the type of
[ML₃·3H₂O]CI₃ (M = La³⁺, Ce³⁺, Pr³⁺, Nd³⁺, Sm³⁺, Gd³⁺, Tb³⁺
and Dy³⁺ and  L = 2-methoxy-4-amino-5-chloro-N-[2-diethylamino)
ethyl] benzamide) have been synthesized and characterized
on the basis of elemental analysis, IR, electronic spectral studies,
molar conductance, magnetic moment and thermal analysis. Except
La³⁺ complex, all other metal complexes are paramagnetic in
nature. The coordination number of the central metal ion in the
present complexes is found to be nine.
