摘要
合成和表征了2个双核铜配合物——酮式-[CU_2(H_2L)Cl]Cl_2和烯醇式-[Cu_2(L)Cl]·H_2O,推知2个配合物分别为酮式和烯醇式,烯醇式配合物中铜离子间的反铁磁相互作用(J=-461.80cm^(-1))大于酮式配合物中的相应值(J=-33.16cm^(-1))。
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).
