Abstract: | This review covers research on coordination compounds of transition metals with stable nitroxyl radicals, in which the nitroxyl fragment is coordinated by the metal ion. Greatest attention is given to generalized aspects of the synthesis of compounds containing a metal-nitroxyl group bond and their magnetic properties in the solid state. Recent developments in the theoretical understanding of the magnetic properties of polycrystalline compounds of this class are discussed. The structure of these complexes and the nature of exchange interactions in them between unpaired electrons of various paramagnetic sites are examined. The review covers studies published in the period from 1980 to 1987. Earlier investigations were reviewed by Larionov 6].Institute of Inorganic Chemistry, Siberian Branch, Academy of Sciences of the USSR.
