摘要：

A new chelating. radical ligand 4ImNNH (2-(4-imidazolyl)-4,4,5,5-tetramethylimidazolin-1-yloxyl-3-oxide) was prepared, and complexation with nickel(II) nitrate gave [Ni(4ImNNH)(2)(NO3)(2)] as a discrete mononuclear complex. Magnetic measurements revealed that [Ni(4ImNNH)(2)(NO3)(2)] had a ground high-spin state (S-total = 2) and exhibited metarnagnetic behavior below 3.4 K. (C) 2003 Elsevier Science B.V.
