Synthesis and Characterization of Lanthanide(III) Complexes with 2,4-pyrimidine diamine-5[(3,4,5-trimethoxy phenyl) methyl]

Abstract

Complexes of La³⁺, Pr³⁺, Nd³⁺, Sm³⁺, Gd³⁺, Tb³⁺ and Dy³⁺ with 2,4-pyrimidine diamine- 5[(3,4,5-trimethoxy phenyl) methyl] have been prepared. The structures of the complexes have been established on the basis of elemental analysis, magnetic moment, infrared, thermal analysis, X-ray powder diffraction and electronic spectra. The complexes are active towards gram-positive bacteria. The ligand is bonded through nitrogen and slight participation with 4f electron in bond formation.
