Synthesis and Characterization of Mercury(II) Complex with Dissymmetric Tetradentate Schiff Base

Abstract

Synthesis of a new mercury(II) complex with a dissymmetric Schiff base ligand is described. The ligand which was prepared from aminothioether pyridine and a salicylaldehyde derivative was characterized by ¹H, ¹³C NMR, FTIR and elemental analysis. The complex of this ligand was synthesized by treating an ethanolic solution of ligand with equimolar amount of HgCl₂ and methanolic NaOH or alternatively by a more direct route in which the two reactants are added to a solution of the ligand immediately after formation of the ligand and prior to any isolation. The complex was characterized by elemental analysis, FTIR, electronic spectra and molar conductivity.
