【摘要】 <正>吡啶取代的氮氧自由基作为稳定的有机自旋载体,由于引入具有强配位能力的吡啶基团使其更易与金属离子结合得到更多结构新颖性质独特的有机-无机杂自旋体系,从而丰富了分子磁学的发展[1-2]。更多还原

【Abstract】 This paper reports a new heterospin complex of [Ni(IM4Py)2(cda)H2O], in which the Ni(II) ion is 6 coordinated by two nitronyl nitroxide radicals, a trident ligand (4-hydroxy-pyridine-2,6-dicarboxylic acid)and one coordinated water to form a three-spins system. The magnetic measurements show that there are weak antiferromagnetic interactions between Ni(II)-radical moleculas with zJ’ = -1.6 cm-1.更多还原
