A 2p-3d hetero-spin complex, namely [Co(hfac)₂(NIT-PyzMe-PhCHO)] (1), where hfac=hexafluoroacetyl-acetone, NIT-PyzMe-PhCHO=2-(3-(1H-imidazol-1-ylmethyl)benzaldehyde)-4, 4, 5, 5-tetramethylimidazoline-1-oxyl-3-oxide, has been successfully isolated and characterized. Complex 1 displays a mononuclear structure. Strong antifer-romagnetic interaction was detected between the Co^Ⅱ ion and the directly coordinated nitroxide group. Moreover, the frequency-dependent out-of-phase signals related to the slow relaxation of magnetization verify the typical single-molecule magnet behavior of the system.
