A Charge-Transfer-Induced Spin Transition in the Discrete Cyanide-Bridged Complex
{[Co(tmphen)2]3[Fe(CN)6]2}
J. Am. Chem. Soc. 126, 6222-6223 (2004)
Abstract:
A charge-transfer-induced spin transition (CTIST) is observed in the discrete
cyanide-bridged complex,
{[Co(tmphen)2]3[Fe(CN)6]2}.
Single-crystal X-ray diffraction, 57Fe Mössbauer spectroscopy, and
magnetic susceptibility were used collectively to describe the oxidation states
of the Co and Fe ions in this cluster as a function of temperature. This
pentanuclear complex represents the first example of a CTIST at the discrete
molecular level.
