Abstract

Abstract: Novel binuclear copper complexes [Cu₂(H₂L)Cl]Cl₂(keto form) and [Cu₂(L)Cl]·H₂O(enol form), where L = N,N'-diisonicotinoyl-2-hydroxy-4-methyl-isophthalaldehyde dihy-drazone, were prepared and characterized.The analytical data show that the copper(Ⅱ) coordinated by ligand is the keto form and enol form respectively, and the anliferromagnetic interaction of enol form(J=-461.8 cm^-1) is larger than that of keto form (J =- 33.16 cm^-1).

Key words: Binuclear Copper complex, Keto form, Enol form, Magnetic exchange interaction
