Abstract
The largest antiferromagnetic coupling parameter was characterized to be 2J/kB = -15.9(2) K in [Gd(hfac)3(6bpyNO)], where 6bpyNO stands for 2,2'-bipyridin-6-yl tert-butyl nitroxide. This molecule was designed according to the empirical relation: more planar chelate favors stronger antiferromagnetic coupling. The Gd-Orad bond is relatively short owing to the tridentate character.
摘要
在[Gd(hfac)₃(6bpyNO)]中，最大反铁磁耦合参数被表征为2J/kB = -15.9(2) K，其中6bpyNO代表2,2'-联吡啶-6-基叔丁基氮氧化物。该分子是根据经验关系设计的：螯合物越平面，反铁磁耦合越强。由于三齿特性，Gd-Orad键相对较短。
