Spectral Studies of Ln(III) Complexes with Pyridine Propanamine-γ-(4-chlorophenyl)-N,N-dimethyl-2-maleate

Abstract

Complexes of La³⁺, Pr³⁺, Nd³⁺, Sm³⁺, Gd³⁺, Tb³⁺ and Dy³⁺ with pyridine
 
propanamine-γ-(4-chlorophenyl)-N,N-dimethyl-2-maleate have been
 
prepared, 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 ligand is bonded through
 
nitrogen of propanamine and nitrogen of pyridine with metal ions. The
 
magnetic moment studies indicate that, it is slightly participation with
 
4ƒ electrons in bonding. The X-ray powder diffraction studies indicate
 
that, the unit cell is monoclinic and space group of complexes is C_2/m or
 
P_c/m. This ligand is anti-histaminic and active towards gram positive and
 
gram negative bacteria.
