  顺磁性配体对“呼吸晶体”中磁结构异常的重要作用

  摘要：

  基于Cu（hfac）2与氮氧化物的聚合物链络合物的呼吸晶体在许多方面都表现出热和光诱导的磁结构异常，这与自旋交叉相似。在目前的工作中，我们报告的合成和Cu（HFAC）的一个新的家庭的调查2层的复合物与叔-丁基吡唑基硝基氧化物及其非自由基结构类似物。具有顺磁性配体的配合物显然在铜（II）配位单元中显示出结构重排，并伴有呼吸晶体的磁性现象。与此相反，它们具有抗磁性配体的结构类似物在铜（II）配位环境中不会发生重排。这在实验上证实了顺磁性配体以及它们与铜（II）离子之间的交换相互作用对于该分子磁体家族中磁结构异常的起着至关重要的作用。
