Framework flexibility and host-guest hydrogen bonding across the phases of a metal-organic perovskite CH3CH2NH3[Mg(HCO2)3]

Abstract: Metal-organic perovskites offer many of the advantages of their ceramic analogues, with a range of exploitable functionality including ferroelectricity. Understanding the structural origins of these properties, however, requires a more detailed description of disorder than is currently available for many materials. Ethylammonium magnesium formate is an ideal candidate to study such behaviour, with two phase transitions involving substantial motion of both the Mg-formate framework and ethylammonium guests, and a polar, potentially ferroelectric structure at room temperature. We propose a total scattering study of the disordered ethylammonium ion as a function of temperature, in order to understand the properties of this material including substantial hysteresis in its phase transitions, and to direct the future engineering of ferroelectric framework materials.
