A bicomponent ion-pair compound with both octahedral and tetrahedral Co^II centers were successfully synthesized and characterized. The octahedral Co^II center undergoes a gradual and incomplete SCO, while the tetrahedral Co^II center shows field-induced single-ion magnetic property. This simple ion-pair strategy should be of great value for the construction of multistable molecular materials.

双组分离子对钴（II）配合物中的慢磁弛豫和自旋交叉行为

具有八面体和四面体Co ^II中心的双组分离子对化合物已成功合成和表征。八面体的Co ^II中心经历了逐渐且不完全的SCO，而四面体的Co ^II中心则表现出场感应的单离子磁性。这种简单的离子对策略对于构建多稳态分子材料应具有重要价值。
