Abstract

The exchange Heisenberg interaction parameters have been determined from theoretical analysis of the temperature dependence of magnetic susceptibility of coordination cluster compounds [Cu(hfacac)₂]₃(Li⁽ⁱ⁾)₂ (hfacac is hexafluoroacetylacetonate, L⁽ⁱ⁾ are 3-imidazoline nitroxides). Upon coordination of both N {dot minus} O oxygens and heterocycle N(3) atoms by Cu²⁺ ions, the interactions are ferromagnetic in nature and have the same order of magnitude. The minor intercluster interactions are antiferromagnetic.
