Summary

Studies of heterospin compounds have led to the creation of new classes of compounds with new combinations of physical characteristics. These include breathing crystals based on Cu(II) coordination compounds (Cu(II) hexafluoroacetylacetonate complexes) with stable pyrazolyl-substituted nitronyl nitroxides. The first part of the chapter summarizes the main features of breathing crystals, obtained using X-ray and magnetic measurements. The second part overviews the results of electron paramagnetic resonance (EPR) study of breathing crystals. The most important consequence of the EPR study of spin dynamic processes in breathing crystals is the applicability of the method of measuring the temperature dependence of the intra-cluster/inter-cluster exchange interaction. Finally, the chapter presents details on the magnetic structure of breathing crystals.
