Effective enhancement of mechanical properties <i>via</i> H/F substitution in 3D cyanide hybrid perovskites
Three-dimensional cyano-bridged organic-inorganic hybrid double perovskites (CHOIPs) exhibit ferroelectricity, ferroelasticity and dielectric switching, but there has been a lack of studies regarding their mechanical properties. Here, we report a giant enhancement in the mechanical properties of CHOIP compounds through H/F substitution. The elastic modulus and hardness of the fluorinated compound (FCH<sub>2</sub>CH<sub>2</sub>NH<sub>3</sub>)<sub>2</sub>[KFe(CN)<sub>6</sub>] are up to twice those of (CH<sub>3</sub>CH<sub>2</sub>NH<sub>3</sub>)<sub>2</sub>[KFe(CN)<sub>6</sub>].
