Abrupt Conversion of Mixed-Valence State in Trinuclear Iron Cyanoacetate Complex
The crystal structure of newly synthesized trinuclear iron cyanoacetate complex, [Fe3O(NCCH2CO2)6(H2O)3], has been determined by single-crystal X-ray structure analysis and found to have a three-dimensional hydrogen-bond network. The temperature dependence of Mossbauer spectrum shows that the complex converts from a valence-trapped state to a valence-detrapped state within a 10 K range.
