Synthesis and Characterization of Some Lanthanide(III) Complexes with N-(Pyrrolidinobenzyl)benzamide

Abstract

A new series of complexes of the lanthanide metal ions, viz., Pr(III), Sm(III), Nd(III), Gd(III) and Dy(III) with a Mannich base derived from benzamide, pyrrolidine and benzaldehyde have been synthesized and characterized. The analytical data include elemental analysis, determination of molar mass, conductivity, magnetic, spectral, thermal, X-ray powder diffraction and antimicrobial studies. The complexes exhibit the following general formula [Ln(PBB)₃] where Ln = Nd³⁺, Pr³⁺, Gd³⁺, Sm³⁺ and Dy³⁺. PBB = N-(pyrrolidinobenzyl) benzamide. All the complexes exhibit octahedral geometry.
