Through-bond magnetic interaction between the 2p spin of the aminoxyl radical and the 3d spin of the metal ions in the complexes of bis(hexafluoroacetylacetonato)-manganese(II) and -copper(II) with 4-(N-tert-butyl-N-oxylamino)-2,2′-bipyridine †

The crystal and molecular structures of 1∶1 complexes of bis(hexafluoroacetylacetonato)-manganese(II), -copper(II) and -zinc(II) with 4-(N-tert-butylaminoxyl)-2,2′-bipyridine were studied by X-ray single crystal analyses to show their mononuclear structures in which the bipyridine moieties are coordinated with the metal ions in a cis configuration and the aminoxyl groups do not take part in the coordination
双(六氟乙酰丙酮)-锰(II),-铜(II)和-锌(II)与1:1配合物的晶体和分子结构4-(Ñ -叔-butylaminoxyl)-2,2'-联吡啶用X射线单晶分析研究了它们的单核结构,其中联吡啶部分与金属离子配位成顺式构型,而氨基二甲苯基不参与配位。在SQUID磁化率仪上测量其磁性能/磁力计揭示锰(II)和铜(II)离子与遥控器耦合。氨基二甲苯自由基通过联吡啶环反铁和铁磁性分别为J / k B = -20.2和+68.7K。
