Abstract

The method of ESR is widely used for the investigation of electronic construction and the geometrical structure of the polynuclear complexes of the transition metals. The majority of the well-known experimental works had been done using monocrystals and polycrystalline examples. Construction of mononuclear complexes of the copper(II), the nature of antiferromagnetic exchange interaction, and its value was the object of the discussion by the scientists and that issue is being checked in the article. Complex compounds of copper(II) with 5,5-dimethyl-2,4-dioxohexane acid ((H₂L¹–H₂L¹¹) methyl ether aroylhydrazones were synthesized and studied. The interaction of alcohol solutions of the H₂L¹–H₂L¹¹ ligands with an aqueous ammonia solution of copper(II) acetate synthesized green fine-crystalline copper(II) complexes. Complexes investigation by the method of ESR spectroscopy, of the studying the magneto chemical properties of copper(II) complexes. If for the complex compound CuL¹ • NH₃, which has a cyclopentanone ring β-diketone fragment, the EPR parameters have theβa substituent for the α²=0.82; value: g=2.099, a_Cu=89.53 e, a_N=12.81 e, then for CuL⁴ • NH₃ with a cyclohexane ring substituent these values are in the range: g=2,101, a_Cu=87,48 e, a_N=13,02 e, α²=0,82.
