Abstract
The exchange Heisenberg interaction parameters have been determined fr om theoretical analysis of the temperature dependence of magnetic susc eptibility of coordination cluster compounds [CU(hfaCaC)2]3(Li((i)))2 (hfacac is hexafluoroacetylacetonate, L((i)) are 3-imidazoline nitroxi des). Upon coordination of both N - O oxygens and heterocycle N(3) ato ms by Cu2+ ions, the interactions are ferromagnetic in nature and have the same order of magnitude. The minor intercluster interactions are antiferromagnetic.
