Dielectric Response Behavior and Displacement-Type Metal-Free Organic-Inorganic Hybrid Phase Transition Material: trans-(NH3C6H10NH3)[NO3]2

Phase transition compounds have been attracting interest in scientific research due to their wide applications in dielectric materials. Herein, a new displacement-type metal-free organic-inorganic hybrid phase transition material trans-(NH3C6H10NH3)[NO3](2) (1) with T-c=245 K has been successfully synthesized. The single-crystal X-ray diffraction elucidates that the space group of 1 turns from P1? in the high temperature phase to P2(1)/c in the low temperature phase. And the reason of phase transition is related to the displacements of trans-(NH3C6H10NH3)(2+) cations and [NO3](-) anions. In addition, 1 shows a dielectric anomaly around the T-c. We expect that this finding will contribute to the research of displacement-type metal-free phase transition materials.
