Abstract
The molecular and crystal structure of Cu(II) bischelate with the deprotonated stable nitroxide radical 4,4,5,5-tetramethyl-2-(2-oxo-1-(4,4,5,5-tetramethylimidazolidine-2-ylidene)ethyl)-4,5-dihydro-1H-imidazole-3-oxide-1-oxylom (HL) are studied. It is revealed that the complex packing is formed of separate CuL2 molecules. Oxygen atoms in >N∂O groups do not participate in Cu2+ ion coordination, and so only weak exchange interactions are observed between paramagnetic centers in CuL2.
