Water‐Switching of Spin Transitions Induced by Metal‐to‐Metal Charge Transfer in a Microporous Framework

Abstract

Water-switchable charge transfer: The microporous hydrated phase {[Fe(Tp)(CN)3]2Co(bpe)}⋅5 H2O shows spin transition induced by metal-to-metal charge transfer (MMCT), but no MMCT is observed in the corresponding dehydrated phase (see picture). Charge transfer can be reversibly switched through de- and rehydration. Tp=hydrotris(pyrazolyl)borate, bpe=1,2-bis(4-pyridyl)ethane. Fe green, Co orange, N blue, O red, C gray, B dark yellow.
