摘要：

Three new metalnitroxide complexes {[Ni(NIT4Py)2(obb)(H2O)2]center dot 1.5H2O}n (1), {[Co(NIT4Py)2(obb)(H2O)2]center dot 2H2O}n (2), and [Co(IM4Py)2(obb)2(H2O)2][Co(IM4Py)2(H2O)4]center dot 10H2O (3) with the V-shaped 4,4-oxybis(benzoate) [NIT4Py = 2-(4-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, IM4Py = 2-(4-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxide, and obb = 4, 4-oxybis(benzoate) anion] were synthesized and structurally characterized. Single-crystal X-ray analyses indicate that complexes 1 and 2 crystallize in neutral one-dimensional (1D) zigzag chains, in which the nitroxidemetalnitroxide units are linked by the V-shaped 4,4-oxybis(benzoate) anions, whereas complex 3 consists of isolated mononuclear [Co(IM4Py)2(obb)2(H2O)2]2 anions and [Co(IM4Py)2(H2O)4]2+ ions. Magnetic measurements show that complexes 1 and 2 both exhibit weak antiferromagnetic interactions between the metal ions and the nitroxides.
