We present a new hybrid compound, namely (Me 2 NH 2 )[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. A new nitroprusside-based hybrid (Me 2 NH 2 )[KFe(CN) 5 (NO)] exhibits thermo-responsive switching behaviours on uniaxial expansivity and SHG signal owing to flexible host-guest hydrogen bonds and the synchronously deformable inorganic framework.
