Coexistence of Magnetic and Electric Orderings in the Metal-Formate Frameworks of [NH][M(HCOO)].

A family of three-dimensional chiral metal-formate frameworks of [NH][M(HCOO) ] (M = Mn, Fe, Co, Ni, and Zn) displays paraelectric to ferroelectric phase transitions between 191 and 254 K, triggered by disorder-order transitions of NH cations and their displacement within the framework channels, com...

      ab: A family of three-dimensional chiral metal-formate frameworks of [NH][M(HCOO) ] (M = Mn, Fe, Co, Ni, and Zn) displays paraelectric to ferroelectric phase transitions between 191 and 254 K, triggered by disorder-order transitions of NH cations and their displacement within the framework channels, combined with spin-canted antiferromagnetic ordering within 8-30 K for the magnetic members, providing a new class of metal-organic frameworks showing the coexistence of magnetic and electric orderings.
