Nitroprusside as a promising building block to assemble an organic-inorganic hybrid for thermo-responsive switching materials

abstract

We present a new hybrid compound, namely (Me2NH2)[KFe(CN)(5)(NO)], possessing a unique nitroprusside-based inorganic host framework in 4-connected sra topology encapsulating organic guest cations. The flexible host-guest hydrogen bonds and synchronously deformed inorganic framework give rise to thermal-responsive switching behaviours on both thermal expansion and nonlinear optical properties during the phase transition at around room temperature.
