摘要
We describe the preparation of the compounds Cu(2-XC6H4COO)2L (X = F, Cl or Br; L = 1-phenyl-2,3-dimethyl-5-pyrazolone or 1,4-dioxane), and compare their spectral and magnetic behaviour with those of binuclear copper(II) acetate monohydrate. The available evidence supports a binuclear structure. The EPR spectra of the powdered solids is consistent with a spin of S = 1. The values of the energy separation (-2J) between the triplet and singlet states indicate a stronger antiferromagnetic interaction in the case of the dioxan adducts than for the 1-phenyl-2,3-dimethyl-5-pyrazolone adducts. © 1979.
