Реферат: This paper reports on our studies of the crystal structures and magnetic properties of five mixed-ligand octahedral complexes of Ni(II) with 3-imidazoline nitroxides Ni(RL)2X2, where RL are deprotonated enaminoketone derivatives of 3-imidazoline nitroxide with different substituents R (CF3, Ph) in the side chain, and X is pyridine, dimethylsulfoxide, or semi-phenanthroline. It is established that this type of heterospin system is characterized by an intramolecular exchange interaction parameter (J) of an order of 10 cm−1. Substitution of the N-donor diamagnetic pyridine or phenanthroline by the O-donor dimethylsulfoxide in the coordination sphere of the metal decreases J by 2–3 cm−3. A transition from trans-to cis-coordination of the enaminoketone ligands and variation of the R substituent in the chelate ring do not affect the value of J.
