摘要：

("Figure Presented") High 'n low: The novel {[Fe(tmphen) 2]3[Os(CN)6]J2} complex (see structure) is the first example of a cluster in which a highspin Fe ||| ion is in a coordination environment of four imine nitrogen atoms and two N-coordinated cyanides. Magnetic studies reveal an unprecedented type of reversible charge transfer induced spin transition (CTIST) between the low-spin Fe||-N≡C-Os||| and high-spin Fe |||-N≡C-Os||| systems. © 2010 Wiley-VCH Verlag GmbH &.
