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, aCu=89.53 e, aN=12.81 e, then for CuL4 • NH3 with a cyclohexane ring substituent these values are in the range: g=2,101, aCu=87,48 e, aN=13,02 e, α2=0,82.
