摘要：
Magnetic properties of the dinuclear cobalt complex originate from the magnetically isolated "asymmetric dimers" where each Co(II) ion within the dimer is situated in the differently distorted octahedral ligand field. Calculated values of magnetic susceptibility, obtained by use of the anisotropic Heisenberg-asymmetric dimer model, are found to be in excellent agreement with experimental chi(T) data over a wide range of temperature (4-295 K). Values of fitted parameters, the exchange integral J and both g-factors of the dimer, are in a very good agreement with the literature data. (C) 2004 Elsevier B.V. All rights reserved.
