Abstract A cyanide-bridged Fe2Co 4,2-ribbon single-chain magnet, {[Fe(bipy)(CN)4]2[Co(phpy)2]} (1, bipy = 2,2-bipyridine; phpy = 4-phenylpyridine) was obtained by the dehydration of {[Fe(bipy)(CN)4]2[Co(phpy)2]}·2H2O (1·2H2O). The electron-transfer-coupled spin transition (ETCST) was achieved during the dehydration process from 1·2H2O to 1, with the electronic configurations transforming from {FeIILS(µ-CN)CoIIILS(µ-NC)FeIIILS} to {FeIIILS(µ-CN)CoIIHS(µ-NC)FeIIILS} (LS = low spin, HS = high spin). The magnetic characterization indicates that the dehydrated 1 exhibits the dehydration-actuated single-chain magnetic (SCM) behaviour.

通过氰化物桥联 Fe2Co 链中的电荷转移脱水驱动的单链磁铁

摘要 氰化物桥连 Fe2Co 4,2-带状单链磁铁，{[Fe(bipy)(CN)4]2[Co(phpy)2]} (1, bipy = 2,2-bipyridine; phpy = 4 -苯基吡啶)通过{[Fe(bipy)(CN)4]2[Co(phpy)2]}·2H2O (1·2H2O)脱水得到。在从 1·2H2O 到 1 的脱水过程中实现了电子转移耦合自旋跃迁 (ETCST)，电子构型从 {FeIILS(μ-CN)CoIIILS(μ-NC)FeIIILS} 转变为 {FeIIILS(μ -CN)CoIIHS(µ-NC)FeIIILS}（LS = 低自旋，HS = 高自旋）。磁性表征表明脱水的 1 表现出脱水驱动的单链磁性 (SCM) 行为。
