Synthesis, Characterization and Thermal Analysis   (TGA and DSC) of Novel Schiff Base Derivatives From 4-Chloro-2-Fluoro aniline and its Complexes with Copper (II) and Nickel (II) Ions

Preparation of Schiff Bases from the Reaction of 4-Chloro-2-fluoroaniline with 3-Ethoxysalicyldehyde (Ligand 1) and 4-Methoxysalicyldehyde (Ligand 2) and Their Complexation with Copper(II) Chloride (1:2) and Nickel(II) Chloride (1:1). characterization on the basis their spectra of 1H-NMR, Fourier transform infrared (FTIR), and Differential scanning calorimetry to assess the thermal characteristics of the produced  (DSC). Elemental analysis and spectral data of the ligands were found to be in a good agreement with their structures, and their complexes with Cu (II) and Ni (II) were synthesized.
