Abstract We describe the preparation of the compounds Cu(2-XC 6 H 4 COO) 2 L (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
摘要 我们描述了化合物 Cu(2-XC 6 H 4 COO) 2 L(X = F、Cl 或 Br;L = 1-苯基-2,3-二甲基-5-吡唑啉酮或 1,4-二恶烷)的制备),并将它们的光谱和磁性能与双核乙酸铜 (II) 一水合物的光谱和磁性能进行比较。现有证据支持双核结构。粉末固体的 EPR 谱与 S = 1 的自旋一致。三重态和单重态之间的能量分离值 (-2 J ) 表明二恶烷加合物的反铁磁相互作用比 1 -苯基-2,3-二甲基-5-吡唑啉酮加合物。
