Nickel(II) and cobalt(II) hexafluoroacetylacetonates react with 4-carbamoyl-2,2-dimethyl-5,5-dimethoxy-3-imidazolin-1-yloxy - a stable nitroxyl radical - to form isostructural coordination compounds M(hfac)2L. The nitroxyl radical acts as a bidentate ligand and coordinates the metal through the imine nitrogen atom and carbamoyl oxygen atom. A model for calculation of the system of exchange clusters Ni(II)-radical is suggested. In terms of this model, Ni(hfac)2L is characterized by ferromagnetic exchange coupling (g = 2.22 ± 0.02, J = 7.3 ± 2 cm-1).
