Dielectric Relaxation and Beyond Limiting Behavior of Alternating‐Current Conductivity in a Supermolecular Ferroelectric

Abstract: A cyclen‐based hybrid supermolecule crystal, [(FeCl2)(cyclen)]Cl (1), where cyclen=1,4,7,10‐tetraazacyclododecane, was prepared using a liquid–liquid diffusion approach. The variable crystal structures exhibit that compound 1 belongs to an orthorhombic crystal system, Pna21 space group (point group C2V) in the temperature range of 150–400 K. This hybrid supermolecule shows a dielectric relaxation behavior around room temperature, and the ferroelectric nature of 1 has been directly verified by hysteresis measur… Show more

“…In general, the structural phase transition of organic–inorganic materials is due to the large freedom of motion triggered by external stimuli of isolated halometallate anions and organic cations. The role of crystallization solvents especially water molecules reported in phase transitions is insufficient. Water molecules can construct a supramolecular hydrogen-bonded network with organic ligands and move or vibrate easily under the influence of energy and external stimuli to be one source for structural phase changes and dielectric relaxation which has highly potential applications in studying basic physical phenomena and exploring electron industry. …”
