N2 - Pucker up! Metal-organic perovskites containing azetidinium cations, [(CH2)3NH2][M(HCOO)3] (M=Mn, Cu, Zn), all show a structural phase transition, coupled with the freezing of the ring-puckering molecular motion of azetidinium cations, and an extremely large dielectric anomaly near room temperature. Molecular dynamics simulations showed the freezing of ring-puckering motion of the four-membered-ring azetidinium cation near room temperature.
