  双核稀土单分子磁体因其简单的磁结构,便于同时调控稀土中心的磁各向异性与磁交换,同时也有利于结合量化计算来提炼各结构因素与单分子磁体性能之间的磁构关系,故而其近年来受到研究者的重点关注[1]。作为本课题组酰腙稀土分子基磁性材料研究[2-4]的延伸,本文在此报道一类双核镝配合物[Dy2L2(OAc)4MeOH2]与[Dy2L2(OAc)4EtOH2](L,2-吡啶甲醛缩2-氨基苯甲酰腙),两者结构类似,均由醋酸根离子桥连两稀土中心而成,而酰腙配体仅作为端基参与配位。但两分子因稀土中心存在有不同的配位溶剂,导致稀土中心的配位场有所差异,最终两分子表现出不同的单分子磁体行为,具体原因仍在进一步研究之中。
