Syntheses and Characterization of Co( Ⅱ ) Schiff Base Chelates and Their Dioxygen Adducts

Abstract

Abstract: One new tetradentate Schiff base ligand L²(L²= N,N-ethylene bis(1-acetylnaphthol-2), two new Co( Ⅱ ) chelates CoL² and CoL³·H₂O(L³ = N,N-phenylene bis(1-phenyl-3-methyl-4-ben-zoyliminepyrazolone-5) and two new dioxygen adducts CoL¹·Py·O₂·2H₂O(L¹=N,N-ethylene bis (l-phenyl-3-methy-4-benzoyliminepyrazolone-5) and CoL²·Py·O₂·2H₂O were prepared and characterized by elemental analysis, IR, UV-Vis, MS, ¹H NMR, ESR, magnetic measurements, thermal analysis and conductivity measurements.

Key words: Cobalt, Dioxygen adduct, Schiff base, Fuction of carrying oxygen
