Characterization of Some Schiff-Base Complexes of Nd(III) in Terms of Electronic Spectral Parameters

Abstract

Fifteen schiff bases derived from veratraldehyde, ethyl vanilline, 2,5 dimethoxy benzaldehyde, methyl acetocetate and ethyl acetoacetate with o^-, m^- and p^- phenylene diamines have been synthesized involving condensation reactions. The fifteen complexes of Nd(III) with the above ligands having general formula out of [M(L₁)(H₂O)₄(Cl)] and [M(L₂)(H₂O)₄(Cl)₃] have been characterized on the basis of IR and various electronic spectral parameters viz. Slater Condon, Lande's and Judd-Ofelt. The study provides useful information about interelectronic repulsion and spin orbit interactions involved in metal ligand bond.
