Abstract

A new metal-radical complex of Mn(II) made up of Mn(hfac)₂ and the radical 4-N-tert-butylaminoxyl-4′-(1-oxyl-3-oxide-4,4,5,5-tetramethylimidazolin-2-yl)biphenyl (BIPNNNO) was synthesized. The X-ray single crystal structural analysis revealed that the complex consists of discrete molecules [Mn(hfac)₂]·(BIPNNNO)₂. The magnetic characteristics of this complex were studied and the Mn–radical and intraradical exchange integrals were evaluated: −135±10 and 72±5 K, respectively. These values are compared with those of complexes of Mn(hfac)₂ with different aminoxyl polyradicals.
