Abstract

A cyanide-bridged tetranuclear complex, [Co₂Fe₂(CN)6- (tp*)₂(dmbpy)₄](PF6)₂•4CH ₃CN (1•4CH₃CN) (tp*: hydrotris- (3,5-dimethylpyrazol-1-yl)borate and dmbpy: 5,5'-dimethyl- 2,2'-bipyridine), was synthesized and its magnetic properties were investigated. Magnetic susceptibility measurements revealed that 1 exhibited an abrupt one-step thermal phase transition based on electron-transfer-coupled spin transition (ETCST) and light-induced ETCST at low temperature.
