Abstract

Two hetero-spin metal–radical complexes [Cu(NIT2Py)2Cl] · ClO4 · H2O ( 1 ) and [Co(NIT2Py)2(H2O)(CH3OH)]  ·  (ClO4)2 ( 2 ) (NIT2Py = 2-(2′-pyridinyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide), were synthesized and characterized structurally and magnetically. The two complexes crystallize in mononuclear structures where two radical ligands coordinate to the metal ion through the nitroxide oxygen atoms directly via the bidentate chelating mode. The magnetic measurements show that two complexes exhibit strong antiferromagnetic interactions between the metal ions and the nitroxide radicals.
