Synthesis And Characterization Of Cobalt(?),Copper(?)and Zinc(?) Complexes With Schiff Bases Derived From 5-Methylsalicylaldehyde

Schiff bases have been widely investigated owing to their various ways of coordination mode.In this article,we use the deprotonated ligands to coordinate with metal element.Two new Schiff bases,C₁₈H₂₃NO?HL¹?,C₂₀H₂₇NO?HL²?and the corresponding complexes with Co?II?,Cu?II?and Zn?II?were synthesized.The compounds are new synthesized.Our work enriched the varieties of Schiff bases complexes.The five complexes'crystal structures were analyzed by Single-crystal X-ray diffraction.The following work:1.Two new Schiff bases were derived from amantadine or rimantadine and5-Methylsalicylaldehyde,respectively.The reactions of Cobalt?II?chloride hexahydrate or Copper?II?chloride dihydrate or Zinc?II?chloride and two bulky Schiff base ligands derived from 5-Methylsalicylaldehyde.Generated six novel complexes,C₃₆H₄₄CoN₂O₂?1?,C₃₆H₄₄CuN₂O₂?2?,C₃₆H₄₄N₂O₂Zn?3?,C₄₀H₅₂CoN₂O₂?4?,C₄₀H₅₂CuN₂O₂?5?,C₄₀H₅₂N₂O₂Zn?6?,respectively.2.The compounds were characterized by IR,UV,melting point,¹H NMR,and molar conductance.The five complexes?complex 1,2,3,4,and 6?were analysised by X-ray single crystal diffraction.
