摘要：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) ]}center dot 2H(2)O (1.2H(2)O). The electron-transfer-coupled spin transition (ETCST) was achieved during the dehydration process from 1.2H(2)O to 1, with the electronic configurations transforming from {Fe-LS(II) (mu-CN)Co-LS(III)(mu center dot NC)Fe-LS(III)). to {Fe-LS(III)(mu-CN)Co-H(S)III(mu center dot NC)Fe-LS(III)} (IS = low spin, HS = high spin). The magnetic characterization indicates that the dehydrated 1 exhibits the dehydration-actuated single-chain magnetic (SCM) behaviour.
